  <h1>goog.ui.TweakUi</h1>
The goog.tweak package provides a convenient and flexible way to add
configurable settings to an app. These settings:
<ul>
  <li>can be set at compile time
  <li>can be set in code (using goog.tweak.overrideDefaultValue)
  <li>can be set by query parameters
  <li>can be set through the TweakUi interface
</ul>
Tweaks IDs are checked by the compiler and tweaks can be fully removed when
tweakProcessing=STRIP. Tweaks are great for toggling debugging facilities.

<h2>A collapsible menu</h2><div id="menu1"></div>
<h2>An expanded menu</h2><div id="menu2"></div>
<ul>
  <li>When "Apply Tweaks" is clicked, all non-default values are encoded into
  query parameters and the page is refreshed.
  <li>Blue entries are ones where the value of the tweak will change without
  clicking apply tweaks (the value of goog.tweak.get*() will change)
</ul>
