				alloc_mol_complex.c

Purpose:
	Allocate memory for an array of MolComplexS structures. The calloc
	function is used to zero-initialize all bytes.

Input:
	No arguments.

Output:
	(1) Memory for an array of MolComplexS structures allocated.
	(2) Return value.

Return value:
	(1) Pointer to allocated memory, on success.
	(2) NULL on failure.
