Calculates the internal energy of the water column with temperature and hypsography

1	internal.energy(wtr, depths, bthA, bthD)

`wtr`	a numeric vector of water temperature in degrees C
`depths`	a numeric vector corresponding to the depths (in m) of the wtr measurements
`bthA`	a numeric vector of cross sectional areas (m^2) corresponding to bthD depths
`bthD`	a numeric vector of depths (m) which correspond to areal measures in bthA

Internal energy is the thermal energy in the water column, which is calculated by multiplying the specific heat of water (J kg-1 K-1) by the temperature and mass of the water in the lake.
