Dragging Faces of Cut Solids

This week I worked on allowing the faces of cut solids to be dragged. The main components of this are:
– changing the base extrude sketch if one of the side faces is dragged
– changing the base extrude height if the top side was dragged
– changing the base extrude sketch location if the bottom side was dragged.

I am now working on box selection, which will allow us to select a group of shapes by clicking and dragging the mouse over them when in selection mode. This is necessary because we need to able to select both a face of a solid to be dragged or the entire solid or sketch shapes for editing.
