I created a Script Extension that, given a class name, instantiates an object with that class. There are some requirements that go along with that concerning how the class code is created, required methods and properties on the class, etc.,
Check out the readme at https://bitbucket.org/tristaanogre/tabledrivenframework for how I did it.
Another article about the same.
I have created a post some time back on this topic, you checkout that.
Also, there is a article on the saem.
