Comparison to the smart limit algorithm in Catlab

[jpfairbanks]

@benjaminmerlinbumpus do you know how the current deciding sheaves algorithm would compare to the smart limit algorithm in Catlab? https://github.com/AlgebraicJulia/Catlab.jl/blob/982ea6ed70d83ddc472abdac69793ff240767e8b/src/categorical_algebra/FinSets.jl#L878

I just talked to @andersenwall about it today and it looks like it is doing something similar to how you compute limits with adhesion_filer in this package
