Merge pull request #19 from certik/readme

Add README
Add geos package
Add the matplotlib-basemap package
Expose the GEOS_DIR variable
Fix basemap's dependencies
Build basemap
Remove unnecessary lines

The GEOS_DIR variable gets created automatically by hashdist, so we don't need
to explicitly create it.
Fix mpl packages installation
Move the mpl specific paths to the mpl package

Now the distutils packge is pristine and has no matplotlib specific hacks.
Initial Travis configuration
Enable verbosity
Use host-blas for default.example.yaml
Use test profiles from the tests/ directory
Workaround for hit behavior

hit tries to find all included yaml files relative to the directory where the
profile.yaml is, instead of the current directory. We fix that by copying the
profile from the tests/ directory.
Install gfortran
Travi: install mpich for host-mpi
Comment out failing packages for now
Split packages1 test into two
Polish the packages2 test
