- Feature #147: force management has been entirely refactored. Now forces can be spatial or constant and surfacic or volumic; the same operator handles all the cases. - Support #337: Yuni::Math::Zero() was too restrictive: its 1.e-6 epsilon for absolute comparison was not low enough. A homemade function has therefore been introduced to replace it. - Feature #320: introduce some geometric functions from Ondomatic: computation of a jacobian and local2global and global2local transformations for 2x2 and 3x3 matrices. - Feature #325: use the new formula to compute jacobian, and prettify ElementaryDataImpl. There is now a class in charge of shape functions calculation at a given quadrature point. The stored matrices are now in a more natural order (attribute called 'jacobian'i sreally so, not a trsnposed of it as it was in Felisce and realier HappyHeart). - Support #316: report the new names for finite elements chosen in code meeting. - Feature #315: a finite element space is now restricted to a given dimension. - Support #193: Remove the clumsy domain restriction I put to make operators work when several dimensions were involved (#315 removes most of the issue!) - Support #70: Rebuild the XCode project; put the xproject file at the root of HappyHeart. - Feature #305: write data in output directory that allows the building of output files in any format.
