 *		The type is an array with NDIMS dimensionality and the size of the
 *      array is DIMS. The total member size should be relatively small.
 *      Array datatypes are currently limited to H5S_MAX_RANK number of
 *      dimensions and must have the number of dimensions set greater than
 *      0. (i.e. 0 > ndims <= H5S_MAX_RANK)  All dimensions sizes must be greater

 * Return:	Success:	ID of new array datatype
 *		Failure:	Negative
