Completing the display errors based on Class type: GSoC Week 10

This week i first completed the code which displays the validation errors based on Class name. I have been able to display the Class errors in a table where the errors are displayed under each class as Error id and the Error description as follows.

After that  i worked on correcting the code written for this feature, after getting the code reviewed from my mentor Wyclif. There were also some feedback for Stop Validation feature and therefore i had to correct them all in this week too.
