Removed an insanely large log file from the Flemming Hansen dispersion data directories.

This is the log file for the CPMGFit analysis.
A large number of fixes for the relaxation dispersion system tested needed for the fix of r21156.

The fix of r21156 changed the format of the keys by which the R2eff/R1rho data is accessed, so many
changes were required.  Additionally, due to slightly better error estimates, all of the tests
using Flemming Hansen's CPMG data needed to be slightly modified.
