Changes output buffering on .res and .burnin files to line buffering.

Fixes #14
Merge branch 'lineBuffering' into develop
Merge branch 'hotfix-9.1.1' into develop
Adds initial YAML configuration file
Completes initial conversion of mpiMcmc
Adds in C++11 Settings files
Pushes the burden of file extension onto the individual application
Adds YAML configurability to sampleWDMass
Changes carbonicity to a double (like it's supposed to be
Removes grid spacing array from sampleWDMass

Per Nathan Stein, "I believe that is just left over from earlier code that evaluated the posterior density on a grid in parameter space. It shouldn't have any effect on sampleWDMass and should be removed."

Removal of the starting input values (only used for the grid spacing) also removes formerly scanf dead code which was being skipped on EOF from the piped configuration file.
Updates the yaml handling to the newest format (with separated priors and sigmas)
Adds yaml configuration to makeCMD
Adds yaml configuration to simCluster
Adds yaml configuration to makeIsochrone
Integrates most recent configuration file format and adds scatterCluster
Removes unnecessary comments from the configuration file
Changes the default configuration settings
Merge branch 'yaml_feature' into develop

Completes #6
Adds a new script file and the BUILD directory
Removes all YAML default values from Settings

I decided it would be better to die if we didn't have a value than to silently provide a default. This may get changed later to print defaulted key:value pairs to stderr (if it seems sensible)
