The molar density of air can be found from the Temperature and Pressure using the ideal gas law.
where the Molar density STP :
from Avagadro's number:
and Loschmidt’s number STP:
And STP Temperature and Pressure:
Write a function that finds the density of air in moles per cubic centimeter for input temperature (in Kelvin) and pressure (in mb).  This function should allow: a single input temperature and pressure pair, a single temperature and vector of pressures, a single pressure and and a vector of temperatures, a vector of pressures and a vector of temperatures of the same size (interpreted as pairs).  Return -1 if a P and T are unequal vector dimensions greater than 1.
