Class
    Foam::seriesProfile
 
Description
    Series-up based profile data - drag and lift coefficients computed as
    sum of cosine series
 
        Cd = sum_i(CdCoeff)*cos(i*AOA)
        Cl = sum_i(ClCoeff)*sin(i*AOA)
 
    where:
        AOA = angle of attack [deg] converted to [rad] internally
        Cd = drag coefficent
        Cl = lift coefficent
 
    Input in two (arbitrary length) lists:
 
        CdCoeffs (coeff1 coeff2 ... coeffN);
        ClCoeffs (coeff1 coeff2 ... coeffN);
