The allocation routines included are for 1D and 2D arrays of the most datatypes that GKlib support. Many of these routines are defined with the help of the macros in gk_memory.h. These macros can be used to define other memory allocation routines.

This function is my wrapper around malloc that provides the following enhancements over malloc: It always allocates one byte of memory, even if 0 bytes are requested. This is to ensure that checks of returned values do not lead to NULL due to 0 bytes requested. It zeros-out the memory that is allocated. This is for a quick init of the underlying datastructures.
