Hello Sir,

I have tried to implement Levene test for checking homogeneity condition.

I have also changed "findStatsCategorical" function in "HypothesisTest.cpp" to give stats for any number of categorical variables (not just two).

I have also added the functionality to let the user choose column whose column mode is not AbstractColumn::Text as an independent variable (containing class labels).

Similarly Levene test can be performed with any number of classes.
