created a validator.js module based on the replybot logic
applied replybot's translateForm function to translate the thankyou screens into the fields array for easier iteration
set up validation checks for fields of type short_text, number and thankyou_screen
created a new method on the ResponseStore class called next that evaluates a field value's validity and returns a next action command to the form
expanded the unit tests for validator.js and responseStore.js to include the validateFieldValue and next logic
included a new instance of TypeError that throws if the validator tries to evaluate a thankyou screen

npm test to check that all tests are passing
npm run dev on localhost:5000 and submit some test answers to the survey
when submitting an answer the form should either: a. allow the user to move to the next question b. alert with an error message and prevent further navigation
