Identify serif and terminal classes

This is very nice and has some terminal names with their visually defining characteristics; would be great to have a fontquant classifier to detect these mathematically based on curve properties

Read the linked article to understand the serif and terminal characteristics shown, then inspect the repository's existing font-analysis entry points and tests. Establish which curve properties can support classification and define tests for the expected classifications; done means the classifier can identify the requested serif and terminal classes mathematically.
