Application updated with Lean body weight

I have consolidated BSA, BMI, IBW and LBW into one single module

I believe there are several variants for the calculation of Lean Body Mass.

The current one used is the

Equation of Boer
Code:

lean body mass for adult males in kilograms =
= (0.407 * (body weight in kilograms)) + (26.7 * (height in meters)) - 19.2
lean body mass for adult females in kilograms =
= (0.252 * (body weight in kilograms)) + (47.3 * (height in meters)) - 48.3

There's also the

James' formula
Code:

Lean Body Weight (men) = (1.10 x Weight(kg)) - 128 x ( Weight2/(100 x Height(m))2)
Lean Body Weight (women) = (1.07 x Weight(kg)) - 148 x ( Weight2/(100 x Height(m))2)

The LBW obtained by the two methods are very similar so I went with one - the Boer formula

If anyone has suggestions for calculation modules, it would help greatly if you link to references which show the formula or algorithm, otherwise it will take much longer, if ever, for your suggestion to be included.
