Conflicts:
	utils/data/mstmip_vars.csv
added example sipnet output
moved approx.posterior function to meta.analysis module, rather than adding a dependency on PEcAn.priors to the PEcAn.utils module (the function requires PEcAn.priors::fitdistr)
fixes redmine #1561 by fixing and renabling tests in the PEcAn.utils package; only the logger functions in utils/inst/tests/test.logger.R don't seem to work, (I have updated the issue with more details)
continuting revisions of the model2netcdf functions and documentation

uncommented tests / removed obsolete tests from test.read.settings; re-added RMySQL dependency
added more informative message if database version is > PEcAn expects. refs redmine #1673
added default database settings so that check.settings will not fail if not specified
removed requirement that settings file have database, model, and run information. Now, only PFT is required
