class_docstr: Subtracts a scalar from each element in the list.
  
  Description:
      Given a list of numeric values and a scalar, subtract
      the given scalar from each value in the list.
  
  Examples:
      >>> subtract_numeric_scalar = SubtractNumericScalar(value=2)
      >>> subtract_numeric_scalar([3, 1, 2]).tolist()
      [1, -1, 0]
code: def get_function(self):
      def subtract_scalar(vals):
          return vals - self.value
  
      return subtract_scalar
