pkg-scicomp: packages in progress

In the pkg-scicomp project a few packages are in progress

• freefem++ a very powerful language to solve pde, right now the remaining issue is updating all files and fix the licence/copyright
• trilinos a meta-package that contains many numerical libraries with an emphasis on robust parallel algorithms. Right now 6.0.19 is in the box, I think I will wait for the version 7
  
• parmetis well parametis is already taken care of by hazelsct but I wanted to modify it and provide some headers from metis. Patches will be sent to hazelsct.
• arprec an arbitrary precision numerical type in C++, I need to update to the last version which fixed licensing issues

I am happy that it is possible to have a large numerical software suite in Debian which you will have difficulties to find in any other distro.
