#9 International Metars: Hecto Pascal Pressure

[Dennis Keller]

The Metarparser currently does not handle pressure
values when identified by the hecto pascal 'Q' designator:

LFBH 271730Z AUTO 35006KT NSC 04/01 Q1011

Reference document:

I think the internationalization process will require
us to expand the Metar data object to maintain units as
well as values. It will be up to the client to ask the
object what unit is being used.

Added logic to MetarParser to handle hecto pascal pressure
representation.

Also added a new accessor metho to Metar
"getPressureInHectoPascals()", which allows extraction in
that format (even though we store all pressure in inHg
internally)
