Determine query language

[scottgonzalez]

We need to figure out how to structure queries for reports.

The simple form of key=value does allow for some play in the value by allowing a special operator as the first character in the value. For example, ~ or % to signify partial string matches or > for numeric matches greater than the value. But this is kind of ghetto since the operator becomes part of the value.

We should see if there's an existing spec for this.

One spec I know about that covers querying is OData. Here's the v3 documentation for querying collections: http://www.odata.org/documentation/odata-v3-documentation/odata-core/#1023_Querying_Collections

There's a mapping of 'dataview' options to OData params here: http://view.jqueryui.com/grid/grid-spf/dataview-odata.js
