Verbose (And Extra Verbose) Logging levels during Indexing about dxr HOT 2 CLOSED

We've got a number of situations where we're using simple "print" statements, as opposed to a logger object. Would a good way to implement this feature be switching to using a logger which can then be configured with the command line arguments?

Right you are! First, yes, the print statements have to die. They were intended just for development but have survived until now. With the inversion of control in place on the "es" branch, DXR itself (rather than its plugins) now controls the looping over files, so we can draw a meaningful progress bar. What do you think of something like I did on https://pypi.python.org/pypi/nose-progressive/? There's a progress bar at the bottom right, a running readout of the current file being worked on on the bottom left, and a scrolling window of errors above. Obviously, when not outputting to a terminal, we wouldn't draw the progress bar. The library behind it, https://pypi.python.org/pypi/blessings/, provides an easy way to take care of that. What do you think?
