Created a couple of new MATLAB functions, INDBVS and SINGLESNPHYPER,
to calculate "single-marker" posterior probabilities when we ignore
correlations between all the markers (i.e. variables).
Fixed the comments for INDBVS and SINGLESNPHYPER.
Created two new functions, SINGLESNPBINZHYPER and INDBVSZBIN, to
compute posterior probabilities and other posterior quantities,
ignoring correlations between the markers (i.e. the variables).
Fixed up the progress updating for SINGLESNPHYPER.
Updated comments for the new functions I created.
