ptarray_construct()

POINTARRAY* ptarray_construct	(	char	hasz,
		char	hasm,
		uint32_t	npoints
	)

Construct an empty pointarray, allocating storage and setting the npoints, but not filling in any information.

Should be used in conjunction with ptarray_set_point4d to fill in the information in the array.
