Ok this is the BYU format (well at least this is what I think is the
	BYU format.)

Line 1 has the number of parts, number of vertices, number of polygons and
	number of elements in the connectivity array.

Line 2 has the start polygon number and end polygon number for part 1
Line 3 has the start polygon number and end polygon number for part 2
.
.
.

Line 18 has the x y z coordinates for vertex 1 and vertex 2
Line 19 has the x y z coordinates for vertex 3 and vertex 4
.
.
.
Line 12715 has the connectivity array for the first polygon
	example:
		1 2 3 -4
	vertex 1 to vertex 2 to vertex 3 to vertex 4 and back to vertex 1

	a negative number show the last vertex of a polygon
