Detailed Description

template<typename T, typename DESCRIPTOR, typename GROUP, typename FIELD>
class olb::GroupedFieldF< T, DESCRIPTOR, GROUP, FIELD >

GroupedFieldF is a NON-PARALLELIZED (no block/super differentiation) functor.

Motivated by enabling easy access to quantities in the particle system, this funcor can be used for any grouped field frameworks. When a proper parrallelization methodology for the particle framework exists, this might have to be extended.
