Matio dependency

[Sylvestre Ledru]

Hello,

We added a (facultative) dependency on matio [1]. We use it to
read/write matlab files.

In order to manage this under Linux, we added a few options: 
* --without-matio => disable matio (warning: m2sci & compatibility
functions will bug)
* --with-matio-include=/path/to/the/includes
* --with-matio-library=/path/to/the/lib

Since this package in not available under any Linux, you will need to
compile it yourself (there is no problem to compile it, just need a
gfortran compiler and zlib).
I created the debian/ubuntu package which is going to be available soon.
