Annealing

Walter de Back requested to merge annealing into master

The Temperature for the CPM Boltzmann sampling can be set with an expression. Primary use for this is simulated annealing in which CPM is allowed to relax to a local energy minimum by setting temperature to 0. See feature request #26 (closed) .

The expression is evaluated once per MonteCarloStep and it value is cached and identical for updated within a MCS. The expression must have global granularity, i.e. homogeneous in space. Thus, spatial variations or cell-dependent temperature (as Marco Scianna has sometimes used) are not allowed.
