Jquery plugin

Here is the jQuery plugin I wrote with the simple example on how to use it.

The code/readme changes make the assumption that the repo gets renamed to Shapeways/ShapeJs so that we can use the repo for all client code surrounding shapejs (rather than just an example). Does anyone have any objections to renaming it?

This code shows bower support, but I have not published to bower yet, I can after everyone approves the code.

The documentation around this needs to be better and we could use a few more example html scripts for uploading stl files and for image popper, etc.
