- moved demo scripts & custom html element to seperate folders
- some minor css cleanup in main index.html
- experimenting with dual way "selection" : selecting a "class" or instance and highlighting
in 3d viewer and vice versa
 * added esmorph lib dependency
 * added pseudo "class" detection , and some code rewrite code
- selecting an object (3D view) and adding a marker in the code editor to see
where it is defined works!
- selecting all instances(in 3d editor)  of a class based on mouse click on its
code works !!
 * very rough for now
 * added instance tracking code injection and handling
 * added various utility code to achieve this
 * only works when selecting the class name eg (Part, Cube)
and not instance names
 * no selection of instances yet
