GIS Tools v0.1.0

Added

• RGB Decomposition tool to generate a color image from dual-pol SAR data, which
  facilitates visual interpretation by decomposing the signals into surface
  scattering with some volume scattering (red band), volume scattering (green band),
  and surface scattering with very low volume scattering (blue band)
• Option to add raster outputs to the map automatically when tool processing is complete
  (set as default for all tools producing raster outputs, but can be turned off in the
  tool dialog if desired)
• README.md for the ArcGIS Toolbox to explain installation and usage

Changed

• For the Scale Conversion and RGB Decomposition tools, the scale (amplitude/power)
  input parameters are automatically populated when using input products that follow HyP3
  naming scheme
