WIP: polymer
Will no longer use google maps in polymer element as this is currently not supported due to interop.js being unable to access non-shadow dom elements inside a polymer element. See https://groups.google.com/a/dartlang.org/d/topic/web-ui/V66biNm0mi4/discussion. Will instead add the google map in index.html and then use polymer for the dialog that pops up when the "add" button is pressed. Currently map and button is displayed, but dialog does not appear.
Map moved to index.html as having it inside the polymer element did not work. Modal dialog transition does not work.
Opening modal input box works. Switched back to using dart widgets again, as it now works with polymer.
Added google map polymer element. Map is displayed and modal dialog to add bar works on top of map.
WIP: Input fields for adding bar.
