Function discrete alloc sp

Another simple version of the allocation functions. This function specifies a single partitioning for defining minimum and maximum claims.

sp = single partitioning

Its arguments are:

• TypeNames: (LUT: Uint8)->ItemName, LandUnitDomain,
• SuitabilityMaps: for each TypeNames { LandUnitDomain->Int32 },
• Regions: UInt16 domain,
• RegionMap: LandUnitDomain->Regions,
• MinClaims: for each TypeNames { Regions -> UInt32 },
• MaxClaims: for each TypeNames { Regions -> UInt32 },
• Threshold: ->Int32
