A proper operator= is added instead, and this should get rid of
the ominous 'uninitialized memory' warning.

I am closing FlySpray entry 437.  Please reopen it if the
problem persists.

 support both versions. Sorry!

Maybe  we can remove it soon if everybody moves to the new naming
scheme.

Code works again and inclusion should, too.

* make iterators only forwarditertors
* remove method getLocalBits
* new methods count and countmasked superseed nSetBits
* nSetBits marked deprecated, but will stay for a possible
  replacement of BitField by BitSetVector<1> (see #456)
* updated test to run the whole iterator test
* fulfill the whole bitset interface

Use assign() method of std::vector to set the entire bitfield.  It is way faster than an explicit for loop
