Feature: Simple clamp AMR indicator.

[jmark]

Refines an element when the element average of variable lies within a given interval [a,b].
Simple, stupid, nothing fancy.

Following Hendrik, I think this is ready to be merged once coveralls passes, i.e., once every dimensional case has been tested.

This has to wait till #2055 is merged since with this equations I use this AMR indicator.
