Necessary changes for the NSE model
  Changes to plotCUB to accurately get the results
  Allow mapBMatNames to set the names in chain$b.Mat[[1]]
    (This allows the visualization to work correctly)

Changes for the NSE model
  Added the ability to update the covariance matrix within my.cubfits.r
  Corrected equation in my.logdmultinomCodOne.r
    Accounted for a2 and removed unnecessary flipping of logMu
    (this was leading to instability in the model)
Merge branch 'master' of https://github.com/GilchristLab/cubfits
Catching up my local copy of cubfits with GilchristLab
Added ... to plotCUB so model and a2 can be passed as arguments
condensed mlogit calculation for potential speedup
Added function to plot CUB for the NSE model
