If we had a file open in that "slot" (A or B) already, and the selected variable name is also present in the new file, pick that.
If that doesn't work, check to see if the selected variable name in the other file (B or A) is present, and if so pick that.
Otherwise stick with the existing default: the first item.

This should speed things up a little bit when bouncing between files, as the variable the user is most likely interested will already be selected.

In the GUI, if the user changes the A variable, and the A and B variables were the same, try to change the B variable to match.

Changed from catching activated to currentIndexChanged, as the former doesn't work when the selection is programmatically changed.

A 0 dimention numpy array is weird.  It's neither a scalar, nor a 1 dimensional array with a single element. "Display Data" silently refused to work for such values.

This change converts the 0d array into a 1d array with a single element immediately before trying to display it.  Result: Display Data now works on 0d arrays, showing the single value as expected.

fix handling of _unsigned attribute in nc files; units=1 no longer display on plots; commands on the command line should be case sensitive; better handling of shape () data

moving the reports and some other things I missed the first time around to use the new constants module

adding a bunch of changes for the new settings tab, but turning the lon/lat stuff back off for now; tweaked the validator for the numbers in the gui so it will allow None; cleaned up bugs in the 1D figure plotting code; added filters to reverse 2D data horizontally or vertically; more cleanup from moving constant values away to a separate module

fixed which doc strings are shown for the inspectStats command; moved gui constants into a separate file; hooked up more of the settings tab; built case insensitive cache for the attributes and variable names in the io module; fixed the validator in the gui so it will accept None as well as doubles

adding mako version dependancy to setup.py; added new stats provider and figure manager to remove those tasks from the model; used partial to simplify the a/b controls/methods in the view

moved to new version to represent the gui change; marked glance no longer zip safe due to mako needing to search directories for templates; moved glance non-code files into the stuff subdirectory; overhauled report generation to remove copied code; more kinds of files can get all variable attributes using io; checked in initial imapp idea plotting code; set up initial stats window in gui; added numeric validation to some gui input fields; changed the statistical analysis constructors to allow for direct use of data objects
