It doesn't allow for claims per region, only minimum and maximum claims for the whole study area, as defined by the second argument. Its arguments are:

• TypeNames: (LUT: Uint8)->ItemName, LandUnitDomain,
• SuitabilityMaps: for each TypeNames { LandUnitDomain->Int32 },
• MinClaims: for each TypeNames { -> UInt32 },
• MaxClaims: for each TypeNames { -> UInt32 },
• Threshold: ->Int32)
