ACT_FUNC - activation function type enumeration

ACT_FUNC = setmetatable({}, {
   __index = {
      CUSTOM = 0,    -- Custom activation function;
      GAUSSIAN = 1,  -- Gaussian activation function;
      LIM = 2,       -- Step activation function;
      LINEAR = 3,    -- Linear activation function;
      LIMLINEAR = 4, -- Threshold activation function;
      POSLINEAR = 5, -- Positive linear activation function;
      SIGMOID = 6,   -- Sigmoid activation function;
      THSIGMOID = 7  -- Hyperbolic tangent sigmoid activation function;
      };
   __newindex = function() print( "Error!!!" ); end;
   });

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