Get all function values [U^C,U^S,...,P^S] at previous timestep t (t=0: present; t>0: previous timestep).

Note: No pressure history is kept, so pressure is always the current value.

Get the function value u in Vector. Note: Given the generality of the interface (this function is usually called from black-box documentation or interpolation routines), the values Vector sets its own size in here.

Reimplemented from oomph::RefineableElement.
