Added datafiles for MINERvA nue Q2 ratio new file: data/MINERvA/CC0pi/MINERvA_CC0pi_nue_Q2Ratio_cov.txt new file: data/MINERvA/CC0pi/MINERvA_CC0pi_nue_Q2Ratio_data.txt

Added a throw statement for if Full and Fast reconfigures don't match in the likelihoods.
Requires one extra reconfigure call but is worth it to stop people getting dodgy fits
when using samples that may not be setup for FAST reconfigures.

Updated covariance scaling. It was out by a factor of 10.0

Fixed covariance path issues. 1DEnu and 1DEpi covariances are still dodgy
for this dataset though (singular)
