        This is a temporary implementation waiting for a more powerful Format.
        The extensions of format compared to MessageFormat are
        - the ability to use context properties {property} - the ability to use more than 10 parameters - '...' is not an escape sequence for the expension
        Parameters:
        format - the string containing the pattern to be replaced
        objects - an array of objects to be formatted and substituted.
        Returns:
        the formated string
