New project: DX_Sample

I have added DX_Samples to http://dxcoreplugins.googlecode.com.

DX_Samples was created in response to a question on the DX_Plugin newsgroup asking for
"a quick example of how I might go making an action that auto-creates regions around any properties that are not already in a region."

DX_Samples contains a plugin called RegionWrapProperties which wraps *all* properties in a class in a region. This is clearly not *exactly* what the original poster asked but we'll get there.

In the mean time we now have a suitable project for creating reference examples about how things can be done, without necessarily needing to create *full* examples.
