As same as netCDF, gribb also can contain in irregular axis (time, isobraric, levels,...) aggregated values, so "directPositions" option in ingredient file must be used to calculate the coefficients for these axes (netCDF).
However, it is more difficult than netCDF because in netCDF, all the variables for each axis could be gotten directly from the API, example:
but for Gribb, it must be iterated all messages to get these values for each axis, then can return the list of coefficients.
It also needed to check the irregular axis handlers in gribb with (pixelIsPoint:false/true).
