- When evaluation produces temporaries in intermediate
steps, they were capture by ref, not properly forwarded.
This results in bugs in more complex cases,
like evaluation of objects returning new arrays expression template.
(preparation for next commit).
- change : all objects are by default
stored now by reference, not by copy any more.
Unless the trait force_copy_in_expr is true.
- rvalue refs are moved into the tree
- simplifies a lot the writing of lazy method, objects.
- added a macro for methods
- tests ok. Further check needed to control absence of copies...
- improved documentation
- All access to grid is now using the [] operator.
() always returns const, and is an evaluation over the domain.
- Now :
* () is always a call to evaluator (or a lazy expression).
* mesh_pt accepted by [] , both const and non const,
and not by ().
- Ported the libs (fourier et al.) but this break API.
