Detailed Description

This command implements a lldb parsed scripted command.

The command provides a definition of the options and arguments, and a option value setting callback, and then the command's execution function gets passed just the parsed arguments. Note, implementing a command in Python using these base interfaces is a bit of a pain, but it is much easier to export this low level interface, and then make it nicer on the Python side, than to try to do that in a script language neutral way. So I've also added a base class in Python that provides a table-driven way of defining the options and arguments, which automatically fills the option values, making them available as properties in Python.
