Namespaces
namespace	warptwin
	Class to propagate CR3BP dynamics in characteristic units.

Functions
int	warptwin::readWMMCoefficientsFile (const std::string &filename, double g[NUMBER_OF_READ_COEFFICIENTS], double h[NUMBER_OF_READ_COEFFICIENTS], double gdot[NUMBER_OF_READ_COEFFICIENTS], double hdot[NUMBER_OF_READ_COEFFICIENTS], double &epoch)
	Reads magnetic field coefficients for WMM from a file and stores them in provided matrices.
double	warptwin::muWMM (double input)
	Unary functional input to the associated Legendre function specific to the WMM model. This is typically denoted as mu or t in literature such as Winch et al. 2005 or Heiskanen and Moritz 1967, respectively.
double	warptwin::dmuWMM (double input)
	Unary functional input to the associated Legendre function specific to the WMM modelm, derivative w.r.t. the functional's input. This is typically denoted as mu or t in literature such as Winch et al. 2005 or Heiskanen and Moritz 1967, respectively.
int	warptwin::schmidtSemiNormLegendreWMM (int N, double x, double *Pcup, double *dPcup)
	Computes the Schmidt Semi-Normalized Legendre function outputs provided the maximum degree (N) as a positive integer. The formula's require that N > 0, and abs(input) <= 1.0.
int	warptwin::schmidtSemiNormLegendreSingularityWMM (int N, double x, double *PcupS)
	Computes the Schmidt Semi-Normalized Legendre function outputs provided the maximum degree (N) as a positive integer when the position is at a singularity. The formula's require that N > 0, and abs(input) <= 1.0.

Variables
const int	warptwin::MAX_HARMONIC_COEFFICIENTS = 12
const int	warptwin::NUMBER_OF_READ_COEFFICIENTS = (MAX_HARMONIC_COEFFICIENTS*(MAX_HARMONIC_COEFFICIENTS+1))/2 + MAX_HARMONIC_COEFFICIENTS
