+====== NB ======
+###
+unsigned integer, read and write
+###
+###
+**Current version does not suport bosons, i.e. NB must always be //0//.**
+###
+###
+An integer representing the number of Bosons in the basis. For Operator //O//, index //0// to //O.NF-1// refers to Fermions, index //O.NF// to //O.NF+O.NB-1// refers to Bosons. Changing this number changes the operator. If the new number of Bosons is smaller than the old number all operators referring to Bosons larger than //NB-1// will be removed from the operator.
