XGC-A08/A09: testing changes in the code that related to problems with particle density evolution

Two input files are generated based on XGC-A07 input file: (1) XGC-A08: same equilibrium and same input file, but older version of the code; (2) XGC-A09: same equilibrium, newer version of the code, but older version of the flow shear suppression model. Left panels show results for the case XGC-A08 and right panels show results for the caseXGC-A09

Results clearly indicated that the problemĀ  has been introduced during the recent merge with the svn repository.
