First commit - After t=0.0305s

Should've been done a long time ago.

Need to copy wallDist to the latest processor time directory every time the simulation restarts.

Started using the omegaWall boundary condition on Omega. No need to worry about that BC anymore.

1.  Started off with deltaT = 1e-05s from t=0. Ran till t=1e-4s.
2.  New run started at t=1e-4s. Same deltaT = 1e-05s.
3.  Changed deltaT to 2e-05s at t=4e-4s.
4.  Changed deltaT to 5e-05s at t=8e-4s. Ran until t=0.001s.
5.  Verified the run on Stampede with visualization.
6.  New run started at t=0.001s. Changed deltaT to 1e-04s.
7.  Changed deltaT to 2e-04s at t=0.0056s.
8.  Changed deltaT to 5e-04s at t=0.0102s.
9.  Changed delta to 3e-04s at t=0.0272s. Done to sync up the write out times.
10. Changed deltaT to 5e-04s at t=0.0275s.
