// Averaging of volume fields or fields on an externally loaded surface.
//
// fields [required]
//     The fields and the specification for the type of averaging needed.
//
// The 'execute' control triggers the averaging.
// The 'output/write' control is optional.
//
// The averaging can be optionally restart in two ways:
//
//   periodicRestart / restartPeriod:
//     - reset at defined intervals
//
//   restartTime:
//     - a 'one-shot' reset at a particular time

//
// fields [required]
//     Pairs of fields to use for calculating the deviation.
//     The fields must already exist on the surfaces.
//
// weightField [optional]
//     A scalar or vector field for weighting.
//
// postOperation [optional]
//     Modify the results by particular operations.
//     (none | sqrt)
//     The sqrt operation is useful when determining RMS values.
//
// The 'output/write' control triggers the calculation.
