Modifies Girardi to update the global isochrone
Makes girardi fixes compile
Fixes segfault related to a default max value being too low
Modifies Girardi to use the msRgbEvol from DSED

This greatly increases the acceptance rate of proposals, leading to actual movement through the parameter space
Makes simCluster compile/run with 9.3
Fixes lack of calls to deriveAgbTipMass in simCluster
#includes constants.hpp so exp10 on Mac works
Integrates David Stenning's carbonicity changes
Adds carbonicity settings to base9.yaml
Makes star modification implicit and removes extra calls to setMags in evolve
Fixes calcPost's signature
Fixes really fixes calcPosts's signature and removes several previous changes from evolve
Removes Chain parameter from logPostStep and replaces with explicit Star vector
Fixes NPARAMS and Settings bugs
Removes Chain from MpiMcmcApplication
Moves base9/Chain.hpp to sampleWDMass (as a temporary measure)

A new chain representing MCMC is going into mpiMcmc, so the old Chain (which was just acting as a container) had to go. sampleWdMass needs to be updated to individually work with a Star vector and Cluster, so it got the old Chain until I fix that
Adds .travis.yml
Changes build directory for Travis-CI
Adds function to compute scaling factor
First-try adaptive burnin

Implements trialIter iteration burnin followed by trialIter iteration trials until trials fall within 20-40% acceptance ratio
