How to code for namespaces

[iklotzko]

Many times this program could be used in the context of a much larger application which uses namespaces (custom, google closures, ExtJS, etc...)

Having no namespace can severely impact the ability to use this library... Fortunately there is an easy solution:

(function (ns) {
    // here is the entirety of 2D.js (or any other library)
    // .
    // .
    // .
    // end of library
    // export functions/classes
    // using very limited list
    ns.Path = Path;
    ns.Shape = Shape;
    ns.Intersection = Intersection
}) (ns);

The reason to wrap this in an immediate executable is to provide closure and variable hiding. We just want to export the publicly accessible objects, functions, etc...
