- #411 Bug corrected: assembling a matrix-vector operator into only a vector or a matrix was actually not compiling. In the process, it's now easier for a developer to provide its own operator with variadic arguments: he no longer has to bother with matrix and/or vector coefficients. - #336 Improve ComputeEltArray implementations; mostly by avoiding memory allocations from Seldon::Transpose (a brand new one has been implemented that performs absolutely no allocation past the initialization). - #206 Hyperelastic case has been cleaned-up; there is for instance no longer Seldon vector or matrix allocation past the initialization phase. - #405 Fix Doxygen compilation, which was screwed when src was renamed into Sources. - #404 XCode template: add new generic files with several layers of namespaces, and improve the current one to handle paths.
