Sofast interface class

[braden6521]

Purpose

Brought SofastCommandLIneInterface up to OpenCSP standards.

Summary of changes

• Moved the common elements of the old SofastCommandLineInterface from /contrib/ into /common/.
• Added an example in the example/sofastFringe directory that uses this new class.
• NOTE: this example requires a working camera, screen, and mirror to run. Thus, I did not set it up to run automatically in the nightlies.

Implementation notes

Since this requires a physical Sofast setup to run, there are no unit tests for this module. Sofast was run in the lab using this module and associated example successfully.
