REVISION SUMMARY
  I have added one way anova test.
  Currently, we can only select one independent column (with multiple levels) and one dependent column.
  
  I have also modified the combo box model for showing columns for tests. Now, QStringList is used as a kind of model for combo box ui.cbCol1 and ui.cbCol2;

TEST PLAN
  Go to hypothesis Test Dock. Select Anova in test and in test_type select One way. 
  Perform Levene Test to check for homogeneity. 
  Click on Do Test to perform one way anova test.
