Add readme.md?

This thin client has thin docs. :smile_cat: Got time to add a quick description of what this is and what the goals are?

At the moment this version of the client is under heavy development. Thus, some parts of the architecture may still change. As soon as we have a first stable version we will provide the necessary documentation. However during the next few days I will provide the basic information about this project. Basically this would be a new version of the following project: http://blog.52north.org/2015/04/13/52north-javascript-sos-client-1-0-official-release/
