Work for project (run_analysis.R)

run_analysis.R's first commit - right now just loads the training data (appropriately labeled) and returns it as a list to the calling environment.
Merges data sets

Loads test data (in addition to train data) and merges the two.  Returns a single data table (dplyr's tbl_df).  There were also some minor formatting changes.
Final commit for project
