main.cpp

/*INSTRUCTIONS
DO NOT CHANGE ANY OF THE CLASSES HERE.
FREE TO INHERIT and OVERRIDE ANY CLASSES
you can make your own classes and functions
Follow the output pattern i am following
Write a function IMT2016*** which takes the file name as a parameter and
completes your task
Add that function to the taskPtrs
In case of any mistakes in my implementation, let me know
Any doubts, post in group

Tasks
1, 2 ,5 ,6 ,7 ,8


INSTRUCTIONS
- Compile using g++ *.cpp
- 2 Modes of running
    -> ./a.out lena.ppm (Runs all tasks)
    -> ./a.out lena.ppm 3 1 2 (Runs tasks 3,1,2 selectively)
