How to design classes in python.

	http://stackoverflow.com/questions/4203163/how-do-i-design-a-class-in-python/4203836#4203836


	#TLDR:
	How to design a class.

	Write down the words. You started to do this. Some people don't and wonder why they have problems.

	Expand your set of words into simple statements about what these objects will be doing. That is to say, write down the various calculations you'll be doing on these things. Your short list of 30 dogs, 24 measurements, 4 contacts, and several "parameters" per contact is interesting, but only part of the story. Your "locations of each paw" and "compare all the paws of the same dog to determine which contact belongs to which paw" are the next step in object design.
