We are redesigning the way we simulate antennas in our loop. To do this, we changed our simulationPEC macro skeletons and our output skeleton. 

To make this easier, we changed the way we name the files, from i.uan where i is the simulation number, to i_j.uan where i is the antenna and j is the frequency.

We also rewrote XFintoARA.py so it's clean. Note that before there were comments from a previous author claiming it was VERY questionably written. This has now been cleaned up. We also changed the bash script relevant to the above changes.

This change needs to be added to the manual, and until we update this update, we have not done it.
