* remove set(), revert to old behavior where = resizes

Browse Source 
* try to be clever in matrix ctors and operator=: be lazy when we can, always allow
  to copy rowvector into columnvector, check the template parameters,
  try to factor the code better
* add missing copy ctor in UnalignedType
* fix bug in the traits of DiagonalProduct
* renaming: EIGEN_TUNE_FOR_CPU_CACHE_SIZE
* update the dox a little
