Getting and Cleaning Data Course Project

This project prepares UCI's Human Activity Recognition Using Smartphones Data Set for further analysis by:

1. Combining the test and train sets
2. Bringing in activity names and subject ids
3. Changing column names to be friendlier
4. Reporting means and standard deviations of the X/Y/Z components of gyroscope and accelerometer measurements, or derivations thereof. (See Set 1's Codebook)
5. provides an additional, aggregated view of the data, taking the mean of each of the fields mentioned above when grouped by activityname and subject id (See Set 2's Codebook)
