Did programming assignment 3
Got the intial data read and merging done.
Implemented the first part of the assignment to generate a tidy_output.txt file that contains only the subject_ID, the Activity Description, and columns for the mean and std variables.
Implemented the second half of the method to product the summary file.
Added a gitignore.
Removed unused data files.
Merge branch 'master' into R_Programming
