Report

As a researcher I should be able to get a standardized report of the data file used, the variables and algorithms specified and the results of the analysis.

> If an analysis has been performed, a button “report” can be clicked and a standardized report is presented in pdf format. The report can be stored in the R-statistical Environment.

No files, tests, or entry points are named. Start by locating the existing analysis flow and how it stores the data file, variables, algorithms, and results; then determine where a Report action and PDF output would fit. Done means an analyzed dataset can produce a standardized PDF report and store it in the R statistical environment.
