Sometimes it might not be needed/wanted to define features with detected peaks in all sample groups. For examples with blanks it might for example be better to exclude them from feature definitions since features with chromatographic peak present only in blanks might not be of interest.
So, we might want support for sampleGroups being a factor with an NA for samples that should be excluded from the feature definition.
