• [x] If no parents have modified OR ancestor modified status then not modified status is set

Tasks:

• [x] Create a method to set the ancestor modified flag of a Word if the parents are modified the Lexicon
• [x] Write Tests for the method
• [x] Test Fail
• [x] Implement method
• [x] Tests Pass
• [x] Verify against Examples
• [ ] Refactor
