UserResolverService

Works like this:

1. Needs a data hash in its constuctor propertyhash, like

{
    data: {
      modulename: 'allex__somenamespace_usertableservice'
    }
}

2. In the constructor a static subservice sink will be acquired, named 'db', sinking the instance of propertyhash.data.modulename instantiated with the very data hash as the propertyhash.

3. user role will expose methods

   • resolveUser
   • fetchUser
   • registerUser
   • usernamesLike
   • usernameExists

4. The methods exposed above will be usable through the EntryPoint instance of the allex_entrypointservice (or its child), via http calls.
