working on it
fixed typo in comment
merged in refactor-pins and made it so that it actually works.
comments and adding TODOs
just leave the connections in #field not in #container
reformatted and commented the debug log section of index.html
fixed the bug where the pin initializer was getting called twice for each connection directive. the problem was that having the html attribute data-sensor on the connection was also linking in the angular directive indicated by sensor, and the same thing for actuator. so i changed the html data attributes on the connection to be data-sensor_id and data-actuator_id to avoid this conflict
