Use this macro to release memory that was allocated by @xref{besALLOC(X)}.
Altough all memory allocated by @xref{besALLOC()} is automatically released when the interpreter thread calling @xref{besALLOC()} finishes it is advised to release all memory chunks, especially large onces when they are not needed anymore.
This macro also NULLifies the argument.
This macro calls the function @xref{alloc_Free()}
