> MergeContent allows specifying the min and max size of a Bin, which is
> typically what we want in order to create reasonably sized bins. However,
> there are times when we have data that necessitates that we stop binning data
> together and create a new bin, because even though the correlation attribute
> is the same, the incoming FlowFile cannot be added to the existing bin. This
> is especially the case when FIFO prioritizers are used and the ordering of
> the data matters.
> To accommodate this, we can add a new "Bin Termination Check" property. If a
> FlowFile causes the check to return a value of {{{}true{}}}, we should merge
> the bin and start a new one.
