reorganize mactower network aging directories

The directory is messy due to the increasing complexity of the project. I decided to make separate folders for the grid-network simulation part and original network part.

drwxr-xr-x   7 hqin  staff   238B Oct 15 11:28 1.ori.ginppit.2015Oct

I copy-pasted some R code into 1.grid.network.2015Oct, but was not certain how to work on it.
