Initial efforts on getting workout logs to parse into java classes.
Added Set.java w/ initial Regex parsing.

 - Modified Exercise back to an interface until a better resolution for inheriting
a static Exercise.parseExercise() solution is found.
 - Added a static parseExercise method to WeightExercise in the mean time.
 - Set is INCOMPLETE; Regexes have yet to be tested, but initial thoughts are down.
   In case it's not clear, the regex will have to grab reps by using a one-or-more qualifier.   Grouping will sort it all out in the end...have fun.
Added biometric profile questionnaire.

Next steps:
1) Write filled profile to file
2) Add proper Date handling
3) Take a picture of the user's face
