-	 *
-	 * This is a fast, fixed-size memory allocator for garbage-collected
-	 * objects.
-	 *
-	 * Memory is allocated from the system on 4096-byte aligned boundaries,
-	 * which corresponds to the size of an OS page in Windows XP.  Allocation
-	 * of pages is performed via the GCPageAlloc class.
-	 *
-	 * In each 4096-byte block, there is a block header with marked bits,
-	 * finalize bits, the pointer to the next free item and "recycling"
-	 * free item linked list.
-	 *
-	 * The bits of the "marked" bitmap are controlled by the SetMark method.
-	 *
-	 * The bits of the "finalize" bitmap are set when an item is
-	 * allocated.  The value for the finalize bit is passed in as a
-	 * parameter to the allocation call.
-	 *
-	 * When the Sweep method is invoked, all objects that are not marked
-	 * with the specified mark flag are disposed of.  If the corresponding
-	 * finalize bit is set, the GCObject destructor is invoked on that
-	 * item.
-	 *
-	 * When an allocation is requested and there are no more free
-	 * entries, GCAlloc will request that a garbage collection take
-	 * place.  It will allocate new blocks if more than 20% of its
-	 * blocks are used after the collection, targeting a 5:1
-	 * heap size / minimim heap size ratio.

-	/**
-	 * GCHeap is a heap manager for the Flash Player's garbage collector.
-	 *
-	 * Memory is allocated from the operating system in large chunks
-	 * aligned on page boundaries (4096-byte aligned).  All allocation
-	 * requests are specified in numbers of 4096-byte pages.  The first
-	 * 4 bytes of each page is reserved for GCHeap's use.
-	 *
-	 * Allocations may fail if there is no free block large enough
-	 * to satisfy the request.  When this occurs, the GC class will
-	 * choose to either garbage collect or expand the heap, and then
-	 * call GCHeap again to retry the allocation.
-	 *
-	 * When blocks are freed, they are coalesced with their neighbors
-	 * when possible to reduce fragmentation.  A "boundary tag" scheme
-	 * similar to Doug Lea's malloc is used to make coalescing fast.
-	 * To keep things simple, coalescing is always performed immediately
-	 * when a block is freed, and not deferred.
-	 *
-	 * Allocations are performed using multiple free lists.  Blocks that
-	 * are <= kUniqueThreshold pages in size get their own free list.
-	 * Blocks above the threshold get mapped to more granular free lists,
-	 * and all blocks above kHugeThreshold get mapped to the last free list.
-	 * This approach is borrowed from Hans Boehm's C/C++ Garbage Collector.
-	 * 
-	 * Free lists are doubly-linked lists sorted in size order.  The
-	 * sorting is done to ensure best-fit allocation.  Each free list
-	 * is itself a list node, and the lists are circular, in a technique
-	 * also borrowed from Doug Lea's malloc.  This makes for very simple
-	 * logic to insert/remove nodes.
-	 *
-	 * Only Windows is currently supported, although this should be easy
-	 * to get working on other platforms.  Memory is allocated in large
-	 * (64K minimum) chunks using the VirtualAlloc API.  Every time the
-	 * heap is expanded, a new heap region is created corresponding to
-	 * the address space returned by VirtualAlloc.  Heap regions are
-	 * allocated contiguously if possible to reduce fragmentation.

-		 * Expands the heap by "size" blocks, such that a single contiguous
-		 * allocation of "size" blocks can be performed.  This method is
-		 * also called to create the initial heap.
-		 *
-		 * On Windows, this uses the VirtualAlloc API to obtain memory.
-		 * VirtualAlloc can _reserve_ memory, _commit_ memory or both at
-		 * the same time.  Reserved memory is just virtual address space.
-		 * It consumes the address space of the process but isn't really
-		 * allocated yet; there are no pages committed to it yet.
-		 * Memory allocation really occurs when reserved pages are
-		 * committed.  Our strategy in GCHeap is to reserve a fairly large
-		 * chunk of address space, and then commit pages from it as needed.
-		 * By doing this, we're more likely to get contiguous regions in
-		 * memory for our heap.
-		 *
-		 * By default, we reserve 16MB (4096 pages) per heap region.
-		 * The amount to reserve by default is controlled by kDefaultReserve.
-		 * That shouldn't be a big deal, as the process address space is 2GB.
-		 * As we're usually a plug-in, however, we don't want to make it too
-		 * big because it's not all our memory.
-		 *
-		 * The goal of reserving so much address space is so that subsequent
-		 * expansions of the heap are able to obtain contiguous memory blocks.
-		 * If we can keep the heap contiguous, that reduces fragmentation
-		 * and the possibility of many small "Balkanized" heap regions.
-		 *
-		 * Algorithm: When an allocation is requested,
-		 * 1. If there is enough reserved but uncommitted memory in the
-		 *    last-created region to satisfy the request, commit that memory
-		 *    and exit with success, also check decommitted list
-		 * 2. Try to reserve a new region contiguous with the last-created
-		 *    region.  Go for a 16MB reservation or the requested size,
-		 *    whichever is bigger.
-		 * 3. If we tried for 16MB reserved space and it didn't work, try
-		 *    to reserve again, but for the requested size.
-		 * 4. If we were able to retrieve a contiguous region in Step 2 or 3,
-		 *    commit any leftover memory from the last-created region,
-		 *    commit the remainer from the newly created region, and exit
-		 *    with success.
-		 * 5. OK, the contiguous region didn't work out, so allocate a
-		 *    non-contiguous region.  Go for 16MB or the requested size
-		 *    again, whichever is bigger.
-		 * 6. If we tried for 16MB reserved space and it didn't work, try
-		 *    to reserve again, but for the requested size.
-		 * 7. Commit the requested size out of the newly created region
-		 *    and exit with success.
-		 *
-		 * If we are able to reserve memory but can't commit it, then, well
-		 * there isn't enough memory.  We free the reserved memory and

-	 * The AtomConstants namespace defines constants for

-	 *
-	 * The atom is a primitive value in ActionScript.  Since
-	 * ActionScript is a dynamically typed language, an atom can
-	 * belong to one of several types: null, undefined, number,
-	 * integer, string, boolean, object reference.
-	 *
-	 * Atoms are encoded with care to take up the minimum
-	 * possible space.  An atom is represented by a 32-bit
-	 * integer, with the bottom 3 bits indicating the type.

-	 *
-	 *  - using last 3 bits means allocations must be 8-byte aligned.
-	 *  - related types are 1 bit apart, e.g. int/double
-	 *
-	 *  kInteger atoms are used to represent integer values from -2^28..2^28-1,
-	 *  regardless of whether the context implies int, uint, or Number.
-	 *  If a number doesn't fit into that range it is stored as a kDoubleType

-//
-//  BigInteger is an implementation of arbitrary precision integers.  This class is used by the
-//   D2A class in mathutils.h to print doubles to greater than 15 digits of precision.  It has
-//   been implemented with that use in mind, so if you want to use it for some other purpose
-//   be aware that certain basic features have not been implemented: divide() assumes the result
-//   is a single digit, there is no support for negative values, and subtract() assumes that the
-//   term being subtracted from is larger than the operand.
-//
-//  By far, memory allocation is the gating speed factor.  D2A never uses more than 8 or so values
-//   during a given run, so a simple memoryCache is used to keep 8 temporaries around for quick reuse.
-//   This would likely have to be adjusted for more general use.
