Transfer documentation

Transfer the Glance Documentation from the Groups page over to the Wiki associated with this repository.

The documentation is currently at: https://groups.ssec.wisc.edu/groups/goes-r/algorithm-working-group/resources-and-recipes/glance-large-dataset-comparison-tools-1

It needs a lot of revision to capture things that have changed since I was updating the documentation more regularly. It probably also needs some reorganization for brevity and clarity.

This is not a complete list of tasks, just things that I had notes about and didn't want to forget. I will probably add more tasks as I review my notes and transfer the documentation.

• Review and rewrite the installation instructions
• Transfer release notes
• Look over the code that processes the config files and make sure all the options are captured in the documentation
• Make more example plots and configuration files for reference
  • Examples for plotDiffs in the basic usage section
  • At least a handful of example config files to illustrate the config usage
• Document the regex syntax for specifying variables on the command line more clearly
• [ ] Change the format of the filters.extract_bit_from_packed_mask parameters to match the new format
• Move Advanced functionality sections
  • Configuration Files
  • Built in Data Filters
  • (Colocating Data)
  • The Glance RPM building instructions
• [ ] Write up details of how to use the Glance GUI
• Example code for how to configure vector plots in a config file (on the Using Configuration Files page)
• Modify the Using Configuration Files page to use the glance.constants instead of hard coded strings
