class_docstr: Class that defines methods for generating code from schemas
  
  Parameters
  ----------
  classname : string
      The name of the class to generate
  schema : dict
      The dictionary defining the schema class
  rootschema : dict (optional)
      The root schema for the class
  basename : string or list of strings (default: "SchemaBase")
      The name(s) of the base class(es) to use in the class definition
  schemarepr : CodeSnippet or object, optional
      An object whose repr will be used in the place of the explicit schema.
      This can be useful, for example, when the generated code should reference
      a predefined schema object. The user must ensure that the schema within
      the evaluated code is identical to the schema used to generate the code.
  rootschemarepr : CodeSnippet or object, optional
      An object whose repr will be used in the place of the explicit root
      schema.
  altair_classes_prefix : string, optional
  **kwargs : dict
      Additional keywords for derived classes.
