adding extra checks when variable data is loaded to prevent crashing and some cosmetic changes to html report output

added global and variable attributes to report pages; fixed bug in the io module that was causing global attributes to never be loaded; corrected the behavior for purple marking circles behind small numbers of mismatch points and added that behavior to some other kinds of mismatch plots

Old behavior was to raise an uncaught exception. Now it reports a warning and continues onward.

"glance info --parsable" now outputs the results in tab deliminated format, repeating the filename on each line, making it easier to parse programmatically. Additional fields may be added later!

At the moment only supports "info".  May add support for other formats later.

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

Returns how many files could not be read, to a maximum of 255 (since the exit code is 8 bit).
This allows other processes calling "glance info" to detect errors.

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.

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.

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

refactoring the stats module and adding more detailed analysis of individual data sets; fixed a bug that caused glance to crash when loading character variables in netcdf files

added ability to restrict histogram range in histogram plotting function; this is all wired up to the inspection report (put histogram_range in the config file to use it); changed set_to_value_between_bounds filter to set_to_value_outside_bounds and wrapped old name for compatibility

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
