DQ Assesment Tool v2.1.0

This minor update incorporates the updated methodology, wherein there are 6 metrics instead of 7. The IAT Outliers metric has been dropped due to its redundancy with sensor uptime. All references to IAT outliers have been removed due to a large number of edge cases that led to non-usable visualizations in the output PDF report. This step has been taken from a user-friendliness readability standpoint.
