Everything so far

`method-list` (for adding breakpoints) isn't ready yet because `core-selector`  is buggy.
The plan is to put `method-list` and `object-tree` on the right side in separate tabs. But `paper-tabs` was  not being compliant with `vulanize`, so that's not done yet.

Requires `O.o()` to work.

Thank you
I'd suggest using standard Closure-style JSDoc type annotations for your params, here and everywhere else. It'll mean that if you want to use a type-checking builder somewhere down the line, you'll have the annotations all ready for all your methods, but also it provides useful documentation for understanding the code as well.
