[Ocaml-lib-devel] De-functor-ized Psqueue

[Brian H. <bh...@sp...>]

Added a create function in place of the old empty.  Fixed queue_to_string 
while I was in there to use a string buffer instead of just endlessly 
concating strings.  This should be more efficient.  Note that priorities 
are still implicitly part of the data.  Not that I'm opposed to making 
priorities just ints, but one major change at a time.

Also todo: to_enum, of_enum, to_stream, and of_stream should be added.  
The to_* should be both by priority and by key.
