License is missing from this repository and needs to be added

@talhasch

Hello, we just observed there is no License file in this repository -- we're interested in developing on top of MultiSafe and extending it via code contributions here but can't do so if there is no license defined since the opaqueness of not having one creates an undefined state of what is permissible use of this code.
