Subject: Merge collections of objects

Hi,

I wonder if there is a quick way to do this.

companyA has 2 employees "a", "b"

companyB has 3 employees "a", "b", "c"

I basically want to merge companyA employess with companyB employees so
when i look at companyA the employees will equal "a", "b", "c"

i know i could do something like companyA.employees = companyB.employees
but this would just overwrite companyA employees so if companyA had more
employees than companyB i would lose the employees companyA had that
companyB didnt.

I think companyA.employees << companyB.employees would just mash them
together and give me duplicates.

The only other way i can think off is a nasty double loop that compares
each object 1 by 1 and then starts again going through the process.

It would also be nice if the employees for companyB were removed but i
could do that separately.

JB
