- Feature #119: GlobalVariationalOperators are now able to support several associated matrices or vectors. - Feature #105/#117: Global matrices and vectors are now held by an external structure rather than by the GlobalVariationalOperators themselves. - Feature #91: LocalVariationalOperators now access only local informations; the extraction from global Vectors occurs earlier. - Feature #100: Some responsibilities of FiniteElement have been given to LocalOperator, following what was decided in code meeting. This was a good decision: much memory is now spared as each FiniteElement no longer need an additional pointer. - Feature #43-#110: there is now a working compilation with Scons; only remaining defect is that I managed to do it only for shared libraries. Linux compilation is foreseen but not yet activated (some options must be determined beforehand with a Linux system handy). - Support #101: Rename GlobalOperator GlobalVariationalOperator.
