Modified .gitignore so that simulated data would be pushed to github
Added simulated rvc and stratum data
modified rvcData to no longer include length frequency data
Including length frequency data in rvcData was kludgey and made the code difficult to understand or maintiain. Decided to move length frequency to its own set of functions.
Modified psu to no longer drop length frequency data (see previous commit)
deleted quantile helper function
Modified strat to check that rvcObj and stratObj either both include or both exclude protected status as a variable
