Getting and Cleaning Data - Course Project
The run_analysis function was designed to combine, summarize, and make clean a

The original data was collected as part of a study designed to explore the
possibility of human activity recognition using smartphones. A full description
is available at the site where the original data was obtained:

This is the un-altered data from the original study linked above that
r_analysis will work it's magic on.
It should be un-zipped and the UCI HAR Dataset directory placed inside your
working directory before running r_analysis.R
It can be downloaded here:
R script that contains the r_analysis function, which takes the original data
set as input and outputs the summarized, tidy data set as a "TidyData.txt" file
in your home directory.
Text file that is produced by running r_analysis() at the R programming prompt
Contains the averages per subject per activity of all the mean and standard
deviation variables from the original dataset
