Creating Features

# TODO

Because typescript does not emit JS, if a value is supposed to be a function it is impossible to determine if a given function is the intended value or a function that returns the actual value. For this reason it is not recommended for any feature types to include properties that are Computable<Function>s, and all functions will be wrapped in computed. The notable exception to this is JSX, which uses a utility function to mark that a function should not be wrapped.
