A gettext compatible i18n library for modern JavaScript Applications

Jed offers the entire applicable GNU gettext spec'd set of
functions, but also offers some nicer wrappers around them.
The api for gettext was written for a language with no function
overloading, so Jed allows a little more of that.

Many thanks to Joshua I. Miller - unrtst@cpan.org - who wrote
gettext.js back in 2008. I was able to vet a lot of my ideas
against his. I also made sure Jed passed against his tests
in order to offer easy upgrades -- jsgettext.berlios.de

// How to pick action names:
//
// * First pick a noun and a verb for the action. For example, if the action is "restart kernel," the verb is
//   "restart" and the noun is "kernel".
// * Omit terms like "selected" and "active" by default, so "delete-cell", rather than "delete-selected-cell".
//   Only provide a scope like "-all-" if it is other than the default "selected" or "active" scope.
// * If an action has a secondary action, separate the secondary action with "-and-", so
//   "restart-kernel-and-clear-output".
// * Don't ever use before/after as they have a temporal connotation that is confusing when used in a spatial
//   context.
// * Use above/below or previous/next to indicate spacial and sequential relationships.
// * For dialogs, use a verb that indicates what the dialog will accomplish, such as "confirm-restart-kernel".
