'Scission' meaning “The act of cutting or dividing, as with an edged instrument”

add diagram

Sometimes complex shapes need to be divided into the smaller pieces. A good example is when creating 'molds' from the pieces of a boolean operation. Or splitting a complex shape from the results of importing into the component pieces, i.e. splitting STL models.

const newshapes = scission(bigshape) // expect an array containing the pieces
