This class represents a robot position with heading. The heading is
automatically adjusted to be in the range -180 to 180. It also defaults
to 0, and so does not need to be used. (This avoids having 2 types of
positions.) Everything in the class is inline so it should be fast.

/// A class for time readings and measuring durations
/**
This class is for timing durations or time between events.
The time values it stores are relative to an abritrary starting time; it
does not correspond to "real world" or "wall clock" time in any way,
so DON'T use this for keeping track of what time it is,
just for timestamps and relative timing (e.g. "this loop needs to sleep another 100 ms").
The recommended methods to use are setToNow() to reset the time,
mSecSince() to obtain the number of milliseconds elapsed since it was
last reset (or secSince() if you don't need millisecond precision), and
mSecSince(ArTime) or secSince(ArTime) to find the difference between
two ArTime objects.
On systems where it is supported this will use a monotonic clock,
this is an ever increasing system that is not dependent on what
the time of day is set to. Normally for linux gettimeofday is
used, but if the time is changed forwards or backwards then bad
things can happen. Windows uses a time since bootup, which
functions the same as the monotonic clock anyways. You can use
ArTime::usingMonotonicClock() to see if this is being used. Note
that an ArTime will have had to have been set to for this to be a
good value... Aria::init does this however, so that should not be
an issue. It looks like the monotonic clocks won't work on linux
kernels before 2.6.
