Compares 2 numeric features that are both witin the same Generic XML set.
Example: compare the distribution of two gene expression predictions of one protein set

The following actions are performed:

2) Calculation of statistic key values like mean,median and standard deviation
3) Histogram and Comparison of each bin
4) Statistical test if the distributions differ within each interval
