* make use of the EvalBeforeNestingBit and EvalBeforeAssigningBit

in ei_xpr_copy and operator=, respectively.
 * added Matrix::lazyAssign() when EvalBeforeAssigningBit must be skipped
   (mainly internal use only)
 * all expressions are now stored by const reference
 * added Temporary xpr: .temporary() must be called on any temporary expression
   not directly returned by a function (mainly internal use only)
 * moved all functors in the Functors.h header
 * added some preliminaries stuff for the explicit vectorization
