Updated and added some code exemplifying how one might naively parallelize the reconstruction of the jets on the grid to compute the actual jet pT.
Added ToDo for both parallelization and for next phase including the gTowers itself
Fixed up parallel. Added example code for serial to compare. Definitely faster to parallelize.
Oops, forgot to add *_serial.py for the example
