Multiple changes to move the project ahead

  Added three dev sketches
  - quadrature_decoder uses the raw addresses of the encoders
    to ensure I can count movement on the installed equipment
  - basic_gw_quadrature wraps the success in the basic
    quadrature in the glow worm framework and validates that it
    works.  You have to turn the wheels by hand for these sketches.
  - dead_band_solver powers the wheels and measures how much
    control effort is necessary to turn them given motor and
    friction constraints.  Initial data from this test was stored
    in the MaryLou.h configuration file.
Added the config file to the repo.

  I need to add a link in the actual Arduino/library folder so that
  this config file is updated and used.
