Added functionality in edge-detection operators

[abdullahranginwala]

Description

Earlier, there were two categories of operations:

• Sobel Derivatives
• Transformation

All the operators within these category had no functionality. Hence, I have merged the operators into one category named 'Edge Detection' which seems more appropriate. I've added functionality for all the operators using object oriented principles.
