api for evaluation of fields in element

[jacobmerson]

Is there a function that evaluates the field at a given location?

It seems like everywhere in the code that's needed we get the components getScalar or eqivalent, then get the shape function values with getShapeVals then multiply.

If it doesn't exist, either Max or I might add an api for it.

We found what we wanted....it is an overload of getScalar
