* Big change in Block and Map:

Browse Source 
- added a MapBase base xpr on top of which Map and the specialization
    of Block are implemented
  - MapBase forces both aligned loads (and aligned stores, see below) in expressions
    such as "x.block(...) += other_expr"
* Significant vectorization improvement:
 - added a AlignedBit flag meaning the first coeff/packet is aligned,
   this allows to not generate extra code to deal with the first unaligned part
 - removed all unaligned stores when no unrolling
 - removed unaligned loads in Sum when the input as the DirectAccessBit flag
* Some code simplification in CacheFriendly product
* Some minor documentation improvements
