Growth Charts UK-WHO

Oct 5, 2017

Faster and slicker interface. Lots of bug fixes and improvements.
Major changes:
- Added BMI centile calculator.
- Added head circumference centiles > 2 years old.
- Graphing is now plotted on a z-score scale (rather than probability), so that centile lines at the extremities are equally spaced out.
- Now displays both z-scores and centiles for the research people out there.
- Age is now also displayed in weeks until 1 year of age (to make it easier to plot on Red Book paper growth charts).
