Removed any inheritance within the scratch-mustache-view steps to make them more flexible.
Set all the scratch-mustache-view step implementations to have default access because they should never be used outside of the steps package.
Implemented the scratch-mustache-view create user steps.
Moved the scratch-mustache-view create user test to the start of the tests before the retrieve tests to be inline with CRUD.
Created null representations of the User and Address classes.
Created the first create user test in scratch-mustache-view.
