Reupped the CSDX project because of weirdness with VS crashing.  Added the point class.  Moved Window related properties to the new window class.  Created IShape interface, could be good for future.  Renamed CSDXCore to Core for less typing.  Updated ExampleSketch.cs with some more stuff.
Merge branch 'master' of https://github.com/SnareHanger/CSDX
