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
Is this a concatenation of Polymer core/paper elements? Can you describe this either in README or in this file? If possible, also mention how to update them (eg, concatenate files X, Y and Z from repo W)
