ReadMe clarity

[camillenoufi]

I am a bit confused on a few things based on the instructions in the ReadMe:

1. Where do we get the .txt file to run on the command line for the program? And how do we know if it is the right format?
2. I would definitely include that it is not necessary to run the code only in Code Blocks. For example, the program runs on a Mac terminal with the following execution once inside the project folder:
   -compile inside folder: g++ -std=c++0x *.cpp -o Motazedi_CSCI2270_FinalProject-master
   -run: ./Motazedi_CSCI2270_FinalProject-master inputfile.txt
