ModifiableSetFromISet<T> class

The ModifiableSetFromISet is a safe, modifiable Set that is built from an ISet. The construction of the set is fast at first, since it makes no copies of the ISet items, but just uses it directly.

If and only if you use a method that mutates the set, like add, it will unlock internally (make a copy of all ISet items). This is transparent to you, and will happen at most only once. In other words, it will unlock the ISet, lazily, only if necessary.

If you never mutate the set, it will be very fast to lock this set back into an ISet.
