Currently, PLANNER-160, already supports

• IntValueRange: from, to, [incrementUnit]
• BigDecimalValueRange: from, to, [incrementUnit]
• DoubleValueRange: from, to

But we want to support more complex ranges, for example
A) every int between 0 and 100 or between 200 and 300. So the range [10-100, 200-300].
B) every int between 0 and 10000 that is not dividable by 7. NOTE: Does anyone really need this?
C) very int that is a prime number. NOTE: that's a big pita to do
D) ...

To support some of these out-of-the-box, we're going to build a ValueRangeBuilder (or ValueRangeFactory), so people don't have to mess around with writing their own ValueRange implementations.

If you have a use case that requires any of those (or another) complex value ranges, please add a comment on this issue and specify which one you need.
