A bit map simply allows to associate a boolean flag to each item of a list, such as a list of entities, etc... numbered between 1 and a positive count nbitems.
The BitMap class allows to associate several binary flags, each of one is identified by a number from 0 to a count which can remain at zero or be positive : nbflags
Flags lists over than numflag=0 are added after creation Each of one can be named, hence the user can identify it either by its flag number or by a name which gives a flag n0 (flag n0 0 has no name)
