Solar Body Parameters

Create a set of parameters that define the characteristics of a human in relation to the sun that falls on them.
These parameters can be plugged into any of the components that estimate mean radiant temperature (MRT) deltas as a result of being in the sun.
posture
A text string indicating the posture of the body. Letters must be lowercase. Default is "standing". Choose from the following:
sharp
A number between 0 and 180 representing the solar horizontal angle relative to front of person (SHARP). 0 signifies sun that is shining directly into the person's face and 180 signifies sun that is shining at the person's back. Default is 135, asuming that a person typically faces their side or back to the sun to avoid glare.
body_az
A number between 0 and 360 representing the direction that the human is facing in degrees (0=North, 90=East, 180=South, 270=West). Default is None, which will assume that the sharp input dictates the degrees the human is facing from the sun.
absorptivity
A number between 0 and 1 representing the average shortwave absorptivity of the body (including clothing and skin color). Typical clothing values - white: 0.2, khaki: 0.57, black: 0.88 Typical skin values - white: 0.57, brown: 0.65, black: 0.84 Default is 0.7 for average (brown) skin and medium clothing.
emissivity
A number between 0 and 1 representing the average longwave emissivity of the body. Default is 0.95, which is almost always the case except in rare situations of wearing metalic clothing.
sol_body_par
A solar body parameter object that can be plugged into any of the components that estimate mean radiant temperature (MRT) deltas as a result of being in the sun.
