whole.lake.temperature: Get volumetrically averaged whole lake temperature
In rLakeAnalyzer: Lake Physics Tools

Calculates volumetrically weighted average whole lake temperature using the supplied water temperature timeseries.

1	whole.lake.temperature(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
