This is (probably) a longer way to locate a particular node/record.

-Was advised to look at enyo.Model#fetch (and/or #parse) to locate the node/record. But it seems to me that those methods only apply when looking at a collection of pre-existing enyo.Model objects. I think we have to first construct enyo.Model objects (more specifically, opflo.StaffInfoModel objects) by wrapping the JSON data from the file. After we do that, we can search/modify our collection with #fetch/#parse.
