The attached patch (based on 3.1.4) makes two changes in libs/cremona/mat*:

  1. Adds getitem methods to the matric class so i,j entries may be extracted;
  2. Changes the conversion to sage of matrices so that matrices over ZZ are constructed instead of ZZ.

These were done as part of a hands-on tutorial William gave to John in Bordeaux.

Replying to @mwhansen:

This is a dupe of #4313

Thanks. One day I'll succeed in creating a new ticket with a pre-existing patch without causing a duplication!
