Optical Properties
******************
Optical property objects provide the absorption, extinction and scattering of
individual molecules/particles in the atmosphere. They are created using the
:class:`ISKOpticalProperty` class and are used by the radiative transfer
engines to calculate scattering, extinction and absorption in the atmosphere. Many optical property
classes are solely focused on the properties of a single molecule while a few classes support
several species (eg Hitran). The majority of optical properties depend upon atmospheric state,  typically
local pressure and/or temperature, and this information is provided to the optical property object as a
climatology and a geographic 4-D location (lat, lon, height, utc).
