-getIntensity(int week) is now complete.
-initial info readout panel shows your weight status (under, normal,
over, obese) and will insult you if you have a BMI over 100.

Added exercise/stretch table, removed stupid.

There is now a huge exercise table! Also, the pointlessly stupid parts
of muscReport are now gone!
