Created a docker with anaconda2 and gcc

[Shikherneo2]

For anyone who wants to avoid the issues with building and installing, I have created a docker repository. https://cloud.docker.com/u/shikhardevgupta/repository/docker/shikhardevgupta/gmmreg_anaconda

Shikhar, thanks a lot for creating this docker repo! FYI, now there is a new repo for the Python implementation of gmmreg: https://github.com/bing-jian/gmmreg-python And this one should work for Python 3. If not, please let me know. Thanks!
