This library can be used to evaluate a function application on a
cluster of machines running a Portable Batch Submission (PBS) system,
like Torque. This functionality is offered by an eval function of
type:
val eval : ('a -> 'b) -> 'a -> 'b Lwt.t
In brief, the closure and its argument are marshalled to another
process which is invoked through a qsub command. The result is
provided through a lwt thread.
Beware, this code is very naive and preliminary, but it's already something.
Contributions and comments are of course welcomed.
