- Feature #564: The interface of Parameter has been refactored; now each instantiation must detail a GetConstantValue() and a GetValue() with the latter taking a quadrature point and a geometric element, The Local->Coords operation is if required performed within the Parameter class; the choice of the nature of the Lua function (local or global) is performed at the definition of the InputParameter object. - Bug #563: Fix the bug forbidding two calls to FEltSpace::ComputeFEltSpaceProgramWiseIndexList(). - Feature #556: Introduce the appropriate Parameter(s) for each model instance. In some of them, there is the requirement they are constant (as variable case would required a heavy rewrite of the model.). - Support #560: Update Seldon to the latest version (still a dev one). - Design #558: Parameter::GetValue() is now overloaded: there is a version that takes a Coords and another that takes a QuadraturePoint. It remains to be seen if the former should be kept; it is actually quite convenient in the definition of transient sources. - Design #557: Make a library for operators; the new hierarchy is: Utilities/ThirdParty < Core < Geometry < FiniteElement < Parameters < Operators < FormulationSolver < Model (but no file compiled at this point for it). - Design #553: Operators in the Elastic model are now defined with the brand-new Parameter class. - Support #543: Use new Seldon library rather than home-made one.
