Added new constructors to MetropolisHastingsSG allowing initial input logPrior and logLikelihood
Modified steps 7, 9, and 10 in the multi-level algorithm to allow for re-use of likelihood values computed by the previous level
Fixed compiler errors for MLSampling.C
Added boolean option initialPositionUsePreviousLevelLikelihood to MLSamplingLevelOptions. This option toggles previous level likelihood caching in MLSampling
Merge remote branch 'upstream/dev' into ml_likelihood_caching
Merge branch 'dev' of https://github.com/libqueso/queso into ml_likelihood_caching
Added directory test_Regression with test program test_GaussianMean1DRegression which does simple estimation of a gaussian mean from an input data set. Updated test/Makefile.am and configure.ac correspondingly
Added help message and the ability to input option values from the command line
Added calculation of exact posterior to test_GaussianMean1DRegression
Remove trailing whitespace and fix some nitpicks
Fix dist error
