Weaver Components should provide an input group component

[jeremythuff]

This input group component should contain a single input of various types. It should allow for both labels and validation to be defined for the input. It should also allow for the definition of event emission on interactions such as onChange, onBlur, onSubmit. Debounce should be supported on event emission.

There is thought needed on how this sort of component could/should interact with a form component.

MVP for this component would be a text input that can emit an event on change. This could be used in the directory app to replace the input used in searching library staff.
