Compares 2 numeric features. The numeric features are read from two
different Generic XML inputs.
Example: Compare the protein abundance distributions of two protein sets.
The following actions are performed:
1) Mann-Whitney and Kolmogorov-Sminorv tests are performed to analyse if both numeric distributions
differ significantly
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
