Classtree generation code

[situx]

Referring to issue #418 I have created source code which extracts 5 different trees from the given ontology model:

• Class tree
• ObjectProperty tree
• DatatypeProperty tree
• AnnotationProperty tree
• Individual tree

The trees are saved in a JS file recources/classtree.js which also includes a function createClassTreeFromJSON(json).
This method can be called in the template e.g. $('#element').jstree(createClassTreeFromJSON(treedata["classes"]) to create a classtree, $('#element').jstree(createClassTreeFromJSON(treedata["objprop"]) for an object property tree etc.
This is shown on my homepage: https://situx.github.io/widoco_classtree/index2.html

This solves the tree generation part of issue #418 but not how to integrate it into the template. This I would like to leave for others to implement as I currently do not know the best approach for it.

Thanks @situx!
This is quite valuable, I need to see how to properly integrate it. I think a lateral sidebar is perhaps the most useful way.

This is useful, indeed! I'd suggest being able to show/hide the sidebar, in order to improve the UX a bit
