	The Difference class allows us to see the difference between two horizontal slices of the same width and height. This allows us to see changes over depth or across velocity models.

	For example, suppose we were interested in knowing where the material properties were softer in CVM-S5 at the surface than in CVM-S4. We could do the following:		For example, suppose we were interested in knowing where the material properties were softer in CVM-S5 at the surface than in CVM-S4. We could do the following:

			<strong>Figure 3</strong><br />
	from pycvm import *<br />		from pycvm import *<br />
	Difference(HorizontalSlice(Point(-120,36,0), Point(-116,32,0), 0.01, "cvms5"), HorizontalSlice(Point(-120,36,0), Point(-116,32,0), 0.01, "cvms")).plot("vs")		Difference(HorizontalSlice(Point(-120,36,0), Point(-116,32,0), 0.01, "cvms5"), HorizontalSlice(Point(-120,36,0), Point(-116,32,0), 0.01, "cvms")).plot("vs")

			<strong>Figure 2</strong><br />
	HorizontalSlice(Point(-119,35,5000), Point(-117,33,5000), 0.01, "cvms5").plot("vs")		HorizontalSlice(Point(-119,35,5000), Point(-117,33,5000), 0.01, "cvms5").plot("vs")

	HorizontalSlice(Point(-119,35,5000), Point(-117,33,5000), 0.01, "cvms5").plot("vs")		HorizontalSlice(Point(-119,35,5000), Point(-117,33,5000), 0.01, "cvms5").plot("vs")

			Please note that the depth is controlled by the first point's depth. Therefore in the above code, the Point(-119,35,5000) class is what specifies that the horizontal slice will be at 5000m depth.
