* the top-level bundle, like "i18n!nls/colors".
*
* This plugin will load the i18n bundle at nls/colors, see that it is a root/master
* bundle since it does not have a locale in its name. It will then try to find
* the best match locale available in that master bundle, then request all the
* locale pieces for that best match locale. For instance, if the locale is "en-us",
* then the plugin will ask for the "en-us", "en" and "root" bundles to be loaded
* (but only if they are specified on the master bundle).
*
* Once all the bundles for the locale pieces load, then it mixes in all those
* locale pieces into each other, then finally sets the context.defined value
