@guj @lizdulac do we still need this?

[guj]

My code is in my "queryDerived" branch. I put in a version of muParser in the toolkit/query/. So no need to import it. This branch is not merged to master yet. Before Liz finishes her parser, It can serve as a backup if Scott wants a demo.

So short answer is no need to add muparser in any builds. Whether to merge this branch to master is up to you.

Liz's version will not use muParser but her own grammar. I assume we'll want to use the same to parse @guj expression from the XML eventually so I don't think we'll need muParser in our builds
