arrays : add ConstView to fix const correctness - A()(0) = 1 will not work any more if A is const, as it should be. - Introduced the notion of const_view, simply done by a flag (flag 0, for easy debug) - changed the slice of ISP to use it (only on C++11 compliant compiler) - Move BoundCheck Flags to 5.

#if defined __GNUC__ || defined __clang__
arrays: new ref counting and weak views - improve the mem_block and shared_block. - the reference counting is now done in the mem_block and shared_block, removing the need of shared_ptr. - speed tests shows that shared_ptr is very slow (due to thread safety?) the new version is much better, though not perfect. - Hence introducing weak views. - also : -- clean the guard mechanism for python (to allow returning from python without any python ref left). -- clean code, add documentation for mem_block -- remove nan init, which was not working, and corresponding test -- serialisation of view still unchanged (need to forbid serialization of view ??). - tests ok, incl. valgrind tests.

icc : workaround macro was not set in the config.h - forgot to declare one cmake var. - test can now be not compiled (Build_Triqs_General_Tools_Test had no effect)

//#warning "gcc compiler" GCC_VERSION
clef : new version using lvalues and moving rvalues - 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
