2. cvglmnet.py fails on some newer versions of numpy on line 260 

contributed by Rachael Mansbach:

I've been using the glmnet python package (great code by the way!) and I've discovered that when trying to run this code with more up-to-date versions of numpy it errors out on line 260 of cvglmnet.py:

 ma = scipy.tile(scipy.arange(nfolds), [1, int(scipy.floor(nobs/nfolds))])

Due to computation of nobs/nfolds as float division rather than int division.  This is easily solved by changing the line to

 ma = scipy.tile(scipy.arange(nfolds), [1, int(scipy.floor(int(nobs/nfolds)))])

but I did have to install from source to get it to work.  It might be worth a note in the installation section or a code update?
