Additional (or adjusted) Scagnostic Ideas

(I had a few of these in a list on my computer so I'm transferring it here. Would be nice to have them all toghether)

• Clumpy3: counts the number of separate alpha hulls (to quote tom "the value of alpha to make three clumps", I'm not entirely sure what that means but it is what my notes said)
• Dense: ratio of the alpha hull and how much of the alpha hull is "filled" (could subtract small area around each point)
