Some boundary conditions might not be applicable to a specific component
but to all components. In this case the optional component id is not
initialized and it is no longer an error.

Improved the time stepper of EvolutionaryPIDcontroller for two phase flow

 as that of the previous rejected step.

Find elements in radius algorithm

 - Use contigiuos memory for start element's nodes.
 - Store sizes of arrays before for-loops.
 - Extract element_in_radius predicate. (This is surprisingly also an optimization.)
 - Revert to depth-first search. Uses vector instead of deque.

This saves repeated squaring.

Randomized tests on 2D and 3D meshes are provided.
