- used during parcel calc() function to flag whether the parcel should be tracked
- if false, parcel not tracked, but sub-models are still active
- useful, e.g. for particle 'stick' condition
- NOTE: stored as a bool, but read/written as a label for restarts/post-processing

field directly.

Renaming Ftot to accelTot to remind that the functions return
accelerations.

calcCoupled/calcNonCoupled arguments and call.

ENH: change some iterator -> const_iterator access

BUG: found some places with forAllIter and ::iterator !

- seems to work more reliably than the previous indented colons

nGrow in 1.6.x was always taken to be 0!

- readFields works seamlessly on-the-fly and as postprocessor
- new surfaceInterpolateFields to create interpolated field
- writeRegisteredObject only check upon writing, not upon startup
- add min,max to faceSource

STYLE: use 'forAll(' NOT 'forAll (', as per coding guide

- improves flexibility and allows more consistent long options

This change allows functionObjects to cleanly terminate the code e.g. on convergence.
