#1396 Remove an unneeded include (which was moreover triggering a warning as it was in experimental directory).

#1385 Make more generic the documentations about copy/move constructor/affectation operator, and starts fixing Geometry missing comments.

#1385 Complete Doxygen documentation so that latest versions of Doxygen may be used without letting warnings.

#1189 In local operators, use optional to compute both unknown and test unknown only when it is meaningful.

#1189 In ElementaryDataImpl, change the way reference finite element are stored: if test unknowns are the same as unknowns the same underlying container is used. C++17 optional feature was used to achieve this (pointer with possible nullptr would have done the same but in a less experessive way).

#905 GlobalVariationalOperator creation changed from pair of unknowns to two arrays of unknowns and test_unknowns. All corrected to reflect this. Still need to change some implementation in ElementaryDataImpl.

#905 Test functions added in all operators. A LOT OF CLEANING is due in the comments parts and the part that was commented out. It is a first try as Sebastien is not there and we did not discuss the whole plan for this feature.

#1039 Modify the include convention so that all paths are preffixed by HappyHeart. The reason is to avoid conflict when library is used in another context (for instance Gautier struggled with HappyHeartVerdandi because he couldn't name his folder with main folder names already used in HappyHeart library).

#1022 Make Darcy a template class with hyperelastic law as argument. Rename a method of ElementaryData classes.
