Sort variables in output from stats & inspectStats.

Put sort directly into for loop; don't bother with giving it a variable.
Use named argument instead of relying on positional one.

glance --version now returns 0

Gui load files

Previously output was ordered in whatever order the set happened to offer them in. This was not stable between different Python versions.  Ordered alphabetically(ish) should be more human friendly, and will simplify the tests.

Previously "glance --version" was treated as an error, and the process's exit code was "9".  Displaying the version isn't an error.

If present, the first one or two arguments to "glance gui" will be automatically loaded as File A and File B.

"glance help FOO" is now case insensitive

Command names are case insensitive.  "glance reportGen" and "glance reportgen" are synonymous.

However, help requests remain case sensitive. "glance help reportgen" fails.  This patch makes it case insensitive.

"python -m glance.compare"→"glance" in documentation

Typo fix: remove extra space.

Typical usage has changed; not usually just invoked through the "glance" binary. Change documentation to match.

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 new density scatter plot and putting limits on how much data glance will be willing to plot in traditional scatter plots and hex plots
