Port to C++: Morphological Transformation.

[amanchhaparia]

Is your feature request related to a problem? Please describe.
Current implementation of Morphological Transformation is in Python, it is needed to be ported in to C++ as discussed in this thread.

Describe the solution you'd like

• Create a .cpp file performing morphological transformation by using necessary OpenCV C++ API.
• Create a Makefile to compile and build the executable.
• Create a Readme.md which contains the detailed explanation of the content similiar to jupyter notebook notes earlier, should contain the instructions to build and execute the code.
