Returns the sensible and latent heat fluxed based on Zeng et al, 1998'

1	calc.zeng(dateTime,Ts,airT,Uz,RH,atm.press,wnd.z,airT.z,RH.z)

`dateTime`	vector of datetime in POSIXct format
`Ts`	numeric value of surface water temperature, degC
`airT`	numeric value of air temperature, degC
`Uz`	numeric value of wind speed, m/s
`RH`	numeric value of relative humidity, %
`atm.press`	atmospheric pressure in mb
`wnd.z`	height of wind measurement, m
`airT.z`	height of air temperature measurement, m (optional)
`RH.z`	height of relative humidity measurement, m (optional)

A data.frame including sensible and latent heat flux estimates, and other variables used in calculating these fluxes.
