Preliminary work on objectGrid.js
Implement object grid

* Wait for two things to complete: the list of attributes, and the findAll
  call for the particular object we are interested in
* Populate a table using all the attributes and all the objects
* Note: This is a very naive implementation, and performance will degrade
  as the datasets get larger--both larger numbers of attributes and larger
  numbers of objects.
* Note: tr, th, td are hard-coded into the file. I'm not sure if this is best
  practice. I did not make use of data-bind or template row features.
