Basic PGM Editor

**NOTE** : Currently tested on Linux and needs a Makefile.

Current Stage : Beta

This is a very simple, command line based, PGM editor created for a college project. It performs image manipulations such as rotations, resizing, and inversion on the PGM format.

The algorithms used for image manipulations are limited to the extent that the project can only handle square PGMs (ie. width = height).

For the future, I might use the QT framework for a GUI and for cross-platform reasons. As I look further into Algorithm Design, there might be a chance for upgrading the current algorithm and to provide multi-threaded support.
