This change was another important step forward. This change implemented the classes and methods involved with calculating attributes of image segments. The system automatically runs all the attribute calculation methods for each segment, stores them in a data structure, and (currently for testing/demonstration) prints them.

I am currently working on implementing methods to calculate other attributes. The difficult part to come will be to determine which attributes will be useful in identifying bloodstains.

Next steps: Install and integrate the database, so that attributes can be stored. This is in pursuit of the vision to have sample data sets, and images that are owned by specific users.
