/**
* The filtering block removes items from this view that are in the parent view.
*
* A YapDatabaseFilteredView will have the same groups and same sort order as the parent,
* with the exception of those groups/rows that the filter block returned NO for.
*
* Here's how it works:
* When you initialize a YapDatabaseFilteredView instance, it will enumerate the parentView
* and invoke the filter block for every row in every group. So it can quickly copy a parentView as it
* doesn't have to perform any sorting.
*
* After its initialization, the filterView will automatically run for inserted / updated rows
* after the parentView has processed them. It then gets the group from parentView,
* and invokes the filterBlock again (if needed).
*
* You should choose a block type that takes the minimum number of required parameters.
* The filterView can make various optimizations based on required parameters of the block.
