Major update, not thoroughly tested yet.  CHREST turtles can now reinforce conscious decision-making and actual actions independently and all CHREST turtles learn visual patterns, conscious decision-making action patterns and actual action patterns and are capable of associating the latter 2 patterns with visual patterns.  Also refactored a lot of other code and added new plots to the interface that track how many times each turtle has used conscious decision-making (with and without visual input) and pattern recognition to select actions.
Enabled model output, included chrest architecture JAR in chrest folder so chrest Netlogo extension operates correctly and deleted unnecessary extension files from top level directory of model.
Includes data left out of previous model file commit due to hasty save.
Fixes bug with continuous model runs

Model now closes all open files at the end of a repeat so that new
repeats are setup correctly.  Also changes the contents of a single
debug message.
Some minor code clean-up
