prop class

Implement a Prop class. Prop class is a composite object with the following attributes:

• nouns : string[], an array of nouns that can describe Prop p
• actions : string[], an array of actions available for the prop
• description : string, flavor text returned when user looks at Prop p
• children : Prop{prop.title:[prop]}, an map of Prop of each child keyed by their title

required methods: readFromTSV(file) : reads a tsv file of prop types

5/26 TODO:

SOLVED: Error was related to how copies of a Prop were made when calling the class method copy() Prop.copy() used copy.copy(), which returned a shallow copy that referenced the original object. Changed Prop.copy() to use copy.deepcopy(), so it now returns a wholly new object with equivalent values.
