missing interface filesystem abstraction for Go

 The missing interface filesystem abstraction for Go. Billy implements
 an interface based on the os standard library, allowing to develop
 applications without dependency on the underlying storage. Makes it
 virtually free to implement mocks and testing over filesystem operations.
 .
 Why billy? The library billy deals with storage systems and Billy
 is the name of a well-known, IKEA bookcase. That's it.
