implement some new shell commands,

Browse Source 
which helps automate system of milling and cutting out shapes
 like arduino uno board etc.

shell commands:

  aligndrill - Create excellon with drills for aligment.

  geocutout  - Cut holding gaps closed geometry.

  del_poly - Remove a polygon from the given Geometry object.

  del_rect - Delete a rectange from the given Geometry object.
