Ability to filter out non relevant fields in the Two Dimensional filter gadget.

Problem Definition

Currently the gadget will display all fields that can be applied regardless of relevance to the filter.

Suggested Solution

We should allow the customer the ability to filter at the very least the fields that don't apply to the filter. We should at least make the Xaxis and Y axis searchable instead of just a list drop down. It's pretty cumbersome for instances that many fields that could apply with no way to filter them out.
