      """A function used to import symbols from modules that may not be available
  
      This function will attempt to import a symbol with the given name from
      the given module, but it will not throw an ImportError if the symbol is not
      found. Instead, it will return a placeholder object which will raise an
      exception only if used.
  
      Parameters
      ----------
      module: str
          The name of the module in which the symbol is defined.
      symbol: str
          The name of the symbol to import.
      msg: str or None
          An optional error message to be displayed if this symbol is used
          after a failed import.
      alt: object
          An optional object to be used in place of the given symbol if it fails
          to import
  
      Returns
      -------
      object
          The imported symbol, the given alternate, or a class derived from
          UnavailableMeta.
