Registry is designed to be a useful helper for managing definitions of JS modules, classes, functions, etc. It provides the ability to define a "thing" using a string identifier and then retrieve it at later date using wildcard matching.
Registry attempts to provide some of the benefits that you find using an IoC in an OO programming environment, but does not force OO patterns into JS like many other Class Helper libraries.
When using registry you should be able to define things in much the same way you are used to. You simply provide them a name that can be wildcard matched in a similar way to eve and retrieved later. Using this technique you can either specifically target a particular thing by using a specific name or a more generalized instance using a more generalized namespace.
Primarily, Registry has been designed for use in the browser but will also work quite happily in a CommonJS environment (such as Node).
At the moment, the tests contain some of the best examples of how Registry can be used, but full documentation will be completed one day...
