For variables who shape is "0" (that is, a simple scalar value), statistics calculations now work.  Although many of the statistics are silly, this is useful for report generation.

Implementation: DataObject has a new function "holding_array" which in most cases returns itself. But if self.data.shape==0, it returns a copy of itself with self.data's scalar value tossed into a single element array.  Now that the data is an array, as expected, the statistics code works fine.

In glance gui, if a variable has only a single value, it will be displayed directly in the "Data shape" field.

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

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

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
