PROC_UNIT - processing unit type enumeration

PROC_UNIT = setmetatable({}, {
   __index = {
      CUSTOM = 0,       -- Custom processing unit;
      RADIAL_BASIS = 1, -- Radial-basis processing unit;
      SCALAR = 2,       -- Scalar processing unit;
      WEIGHTED_SUM = 3  -- Weighted sum processing unit;
      };
   __newindex = function() print( "Error!!!" ); end;
   });

The object provides a set of read-only numeric fields, each of which corresponds to a particular processing unit.
