Changed specifics around operators as a whole

* Instead of checking the ASCII values of tokenChar and evaluating the contents that way, a isdigit(), isalpha, and isspace() is used.
* Getting WS after '}' is acceptable and has been changed from being an error
* When nextState is an error code and then assigned to currState the next line travels FSA based on that error code. A check of currState's polarity is made and if it passes nextState can be evaluated
