Is pandaPIparser case-sensitive? #11

Description

@rpgoldman

I notice with the following domain file that I get this message from the parser:

There is no declaration of the subtask drive-ta in the input
Method move-one-ta has the subtask (__t_id_3) drive-ta. The task is declared with 0 parameters, but 2 are given in the method.
There is no declaration of the subtask drive-ta in the input
Method move-more-ta has the subtask (__t_id_5) drive-ta. The task is declared with 0 parameters, but 2 are given in the method.

The action is declared using drive-TA with caps. PDDL is case-insensitive, so I think HDDL should be also, shouldn't it?

Indeed, down-casing the action definition makes this message go away.

Here's the domain:

(define (domain toll-domain)
