Added DXF R2000 vector logo.
Basic implementation of import.

import works for simple cases.  Still work to do on finding the right
script, and setting globals/locals correctly when running an imported
function.
Add note about implementing inplace operators.
Change mp_compile so that it returns a function object for the module.
