GEM case test fails between two commits in branch amaya-library #24

The only reason the test fails is because the process distribution was different in each test: 4 processors were used. In the first run I employed XLEN=2 and YLEN=2. In the second run XLEN=4 and YLEN=1. The plots for the energy conservation are very similar but there is a small difference between the two runs. We should take a look at the effects of processor distribution and number of processors on the results. |

Processor distribution seems to play a role in the final results of the simulation. The GEM case gives slightly different results depending on how the cartesian grid is distriuted between the processors. A small correction of the for loop boundaries was performed in the perfect conductor subroutines.

A change between commit 9a08b6f and the following commit 455d8fc produced a small change in the results of the GEM test case.
The major modification between these two commits was the update of the perfectConductor subroutines. Reverting this change doesn't seems to make any difference.
