ng-planetaryjs looks for global with AMD loader

While using RequireJS to AMD load ng-planetaryjs, planetaryjs, and their dependencies, ng-planetaryjs still looks for global object planetaryjs (such as in ```var globe = planetaryjs.planet();```). Thus use the UMD pattern "AMD with global, Node, or global" instead of "AMD, Node, or browser global" from https://sublime.wbond.net/packages/UMD%20snippets .
