Family operator strategies

Operator overload	Strategy	Purpose	Membership scope	Source description
<(varbit,varbit)	1	search	Family member	less than
<=(varbit,varbit)	2	search	Family member	less than or equal
=(varbit,varbit)	3	search	Family member	equal
>=(varbit,varbit)	4	search	Family member	greater than or equal
>(varbit,varbit)	5	search	Family member	greater than
