Missing implementation for COSMAS II-Prox-Option min/max.

[Bodmo]

There is currently no implementation for the Min-/Max hit grouping option od the Prox-Operator of COSMAS II.
Ex.
Q1 = A /s0 B (default for max).
Q2 = A /s0,max B (same as Q1).
Q3 = A /s0,min B (missing implementation)

The ANTLR-output of Q2 and Q3 contains a distinct info for that:

Q2 -> ANTLR -> GRP MAX
Q3 -> ANTLR -> GRP MIN

But in both generated KoralQueries, the distinction is missing.
The default for the KoralQuery seems to be the min-group.
