/* 
	Mesh.h
	Mesh will store the vertices(vec4's) in a 2D vector.  There will be a
	default set of vertices, but the user can change the number of columns
	and rows.  The user can also change the width of each row.  The 
	vertices will be used to draw the faces in a mesh 

	Use algebra3 to store xyz coordinates as vec4 objects
