u"""filenav for Pythonista, version 2, by dgelessus.
This is the "slim" version of filenav 2. It consists of a single
navigable table and is thus ideal for use on an iPhone or iPod touch, or
even on an iPad in popover mode.

A separate version intended for larger screens can be found under
`full.py`. It is designed to be run in panel mode on an iPad, though it
may also be usable on large iPhones in landscape mode.
