geometry_type_from_string()

int geometry_type_from_string	(	const char *	str,
		uint8_t *	type,
		int *	z,
		int *	m
	)

Calculate type integer and dimensional flags from string input.

Utility function to get type number from string.

Case insensitive, and insensitive to spaces at front and back. Type == 0 in the case of the string "GEOMETRY" or "GEOGRAPHY". Return LW_SUCCESS for success.
