rename the method count() to use_count().  This is the naming of the standard shared-pointer implementation

principle of least surprise: executables should have the same name as the source file that contains main()

Note that the current implementation of the determinant is rather
subobtimal.  While it is rather efficient, it is neither the most
numerically stable way to compute the determinant, nor does it work
for integers.  But I think it is much better than no implementation at
all.

* 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
