Adding notes about particle deposit fields.

[matthewturk]

This adds -- and removes! -- documentation about particle deposit fields.

Fixes #2218.

Would this be the place to mention ParticleProjectionPlot or should that be somewhere else? We already have docs for it but it would be good to link it somewhere.

[matthewturk]

Sure -- would you mind suggesting a change?
