Class UpToTwoPositiveInt64Outputs

An FST Outputs<T> implementation where each output is one or two non-negative long values. If it's a output, is returned; else, TwoLongs. Order is preserved in the TwoLongs case, ie .first is the first input/output added to Builder<T>, and .second is the second. You cannot store 0 output with this (that's reserved to mean "no output")!

NOTE: the only way to create a TwoLongs output is to add the same input to the FST twice in a row. This is how the FST maps a single input to two outputs (e.g. you cannot pass a UpToTwoPositiveInt64Outputs.TwoInt64s to Add(Int32sRef, T). If you need more than two then use ListOfOutputs<T>, but if you only have at most 2 then this implementation will require fewer bytes as it steals one bit from each long value.

NOTE: the resulting FST is not guaranteed to be minimal! See Builder<T>.

NOTE: This was UpToTwoPositiveIntOutputs in Lucene - the data type (int) was wrong there - it should have been long
