how to start using nubs

let's add some cool nub devices to your html <body>
- ```
<nub-stick></nub-stick>
```
  - it's a mobile-friendly thumbstick!
  - it will emit nub_cause events
- ```
<nub-pointer></nub-pointer>
```
  - also emits nub_cause events
  - this one doesn't render any ui (all of the "real" devices are like this)
wrap your nub elements inside a <nub-context>
```
<nub-context>
  <nub-keyboard></nub-keyboard>
  <nub-pointer></nub-pointer>

  <nub-stick name=Stick1></nub-stick>
  <nub-stick name=Stick2></nub-stick>
</nub-context>
```
- nub-context is for grouping nub devices
  - the context will only listen to devices nested under it
  - the context may contain devices and editing ui
- nub-context introduces bindings
  - bindings define the associations between "causes" and "effects"
  - nub-context has ui that allows users to edit their bindings
  - an example cause might be KeyW
  - an example effect might be forward
  - in most cases, you probably want your app to listen to nub_effect events like forward rather than the causes

understanding cause and effect in nubs

nub_cause events: like keyboard key presses and mouse movements. all nub devices like <nub-keyboard> or <nub-stick> dispatch these events.
nub_effect events: like "forward" or "open menu". these are dispatched by a <nub-context> element, based on the user's bindings. the bindings allow users to customize which effects are triggered by which causes.

devices

<nub-keyboard> (real device) listens to real mouse or touch inputs.
<nub-pointer> (real device) listens to real keyboard inputs.
<nub-stick> (virtual device) mobile-friendly thumbstick.
<nub-stickpad> (virtual device) thumbstick area, which centers the stick wherever your touch starts.
<nub-lookpad> (virtual device) area for tracking touch movements, to emulate a mouse.
<nub-gridboard> (hybrid device)

bindings, editing, and troubleshooting

<nub-context> listens for nub_cause events, and dispatches nub_effect events, based on the current bindings. only listens to nub_cause events nested within the nub-context element.
<nub-editor> interface for users to customize their bindings.
<nub-visualizer> see what's going on, which nub_effect events are being dispatched.
