class_docstr: Class to hold the default value of a Param and rule set to do the validations.
  
  Without the rule set it always validates and returns the default value.
  
  :param default: The value this Param object holds
  :param description: Optional help text for the Param
  :param schema: The validation schema of the Param, if not given then all kwargs except
      default & description will form the schema

docstr: Run the validations and returns the Param's final value.
  
  May raise ValueError on failed validations, or TypeError
  if no value is passed and no value already exists.
  We first check that value is json-serializable; if not, warn.
  In future release we will require the value to be json-serializable.
  
  :param value: The value to be updated for the Param
  :param suppress_exception: To raise an exception or not when the validations fails.
      If true and validations fails, the return value would be None.
