 * etchmem.h -- heap memory allocate and free.
 * The c binding wraps the heap allocator in order to track allocations. we supply 
 * the etch_malloc macro which, when ETCH_DEBUGALLOC is defined,  will accept module 
 * name and code line number, along with object type and allocation size, in order  
 * to track heap allocations and frees, and to subsequently report memory leaks.
