VelocityDbHashSetTIsSubsetOf Method

Checks if this is a subset of other. Implementation Notes: The following properties are used up-front to avoid element-wise checks: 1. If this is the empty set, then it's a subset of anything, including the empty set 2. If other has unique elements according to this equality comparer, and this has more elements than other, then it can't be a subset. Furthermore, if other is a hashset using the same equality comparer, we can use a faster element-wise check.
