Dependencies and documentation

[mjafin]

Hi there, Many thanks for releasing gossamer to the community. I had a few issues trying to use it, namely the documentation is quite sparse and in a typical HPC environment the dependencies are quite restricting. We use CentOS6 and e.g. libboost is 1.41.0 so gossamer won't compile.

Any chance you could release precompiled binaries compiled on older servers? Like what bioconda are doing, http://bioconda.github.io/
