Interpolated continuous phase data is only needed during a track and
therefore shouldn't be stored on the parcel. The continuous velocity,
density and viscosity have been moved from the kinematic parcel to the
kinematic parcel tracking data. This reduces the memory usage of the
kinematic layer by about one third. The thermo and reacting layers still
require the same treatment.

The patch can be determined from the particle when it is needed. Most of
the time it is not.

A lot of methods were taking argument data which could be referenced or
generated from the parcel class at little or no additional cost. This
was confusing and generated the possibility of inconsistent data states.

Tracking data classes are no longer templated on the derived cloud type.
The advantage of this is that they can now be passed to sub models. This
should allow continuous phase data to be removed from the parcel
classes. The disadvantage is that every function which once took a
templated TrackData argument now needs an additional TrackCloudType
argument in order to perform the necessary down-casting.

Temporal variation of Ta is generally more useful than spatial variation but
a run-time switch between the two modes of operation could be implemented in
needed.

"pos" now returns 1 if the argument is greater than 0, otherwise it returns 0.
This is consistent with the common mathematical definition of the "pos" function:

https://en.wikipedia.org/wiki/Sign_(mathematics)

However the previous implementation in which 1 was also returned for a 0
argument is useful in many situations so the "pos0" has been added which returns
1 if the argument is greater or equal to 0.  Additionally the "neg0" has been
added which returns 1 if if the argument is less than or equal to 0.

Now the "localEuler" ddt scheme does not apply any corrections due to
mesh-motion; the old-time volumes are not used and the mesh-motion flux is set
to zero.  A consequence of these changes is that boundedness of transported
scalars is ensured but mesh-motion causes a conservation error which will
reduces to zero as steady-state is approached and the mesh becomes stationary.
