%   Input:      alt:        Final Geometric Altitude[km]
%               division:   Reporting points for output arrays[km]
%                           （.01 km & Divisible by .01 km）
%               units:      1-[Metric]
%                           2-{English}
%   Default:    Values used if no input
%               alt:        1000 km
%               division:   1 km
%               units:      Metric
%   Output:     Each value has a specific region that it is valid in with this model
%               and is only printed out in that region
%               Z:          Total Reporting Altitudes[0<=alt<=1000 km][km]{ft}
%               Z_L:        Lower Atmosphere Reporting Altitudes[0<=alt<=86 km][km]{ft}
%               Z_U:        Upper Atmosphere Reporting Altitudes[86<=alt<=1000 km][km]{ft}
%               T:          Temperature array[0<=alt<=1000 km][K]{R}
%               P:          Pressure array[0<=alt<=1000 km][Pa]{in_Hg}
%               rho:        Density array[0<=alt<=1000 km][kg/m^3]{lb/ft^3}
%               c:          Speed of sound array[0<=alt<=86 km][m/s]{ft/s}
%               g:          Gravity array[0<=alt<=1000 km][m/s^2]{ft/s^2}
%               mu:         Dynamic Viscosity array[0<=alt<=86 km][N*s/m^2]{lb/（ft*s）}
%               nu:         Kinematic Viscosity array[0<=alt<=86 km][m^2/s]{ft^2/s}
%               k:          Coefficient of Thermal Conductivity
%                           array[0<=alt<=86 km][W/（m*K）]{BTU/（ft*s*R）}
%               n:          Number Density of individual gases
%                           （N2 O O2 Ar He H）[86km<=alt<=1000km][1/m^3]{1/ft^3}
%               n_sum:      Number Density of total gases

%   Notes:                  Program uses a 5-point Simpson‘s Rule in 10
%                           meter increments.  Results DO vary by less 1%
%                           compared to tabulated values and is probably
%                           caused by different integration techniques
%   Examples:               atmo（） will compute the full atmosphere in 1 km
%                           increments and output in Metric Units
%                           atmo（10） will compute
