Public Attributes
unsigned int	N_dim
	spatial dimensions of current problem (2d or 3d)

double	Omega
	pattern speed of rotating potential

CBasicOdeIntegrator::STEPPERKIND	integratorType
	type of ODE integrator

double	accuracyRel
	relative accuracy parameter for variable-timestep integrators (except IAS15)

double	accuracyAbs
	absolute accuracy parameter for variable-timestep integrators (except IAS15)

double	accuracyIAS15
	accuracy parameter for the IAS15 integrator

double	accuracyTreecode
	factor in leap-frog timestep selection for the treecode potential

bool	treecodeSymmetrizeTimestep
	whether to use time-symmetrized leapfrog (Hut, Makino & McMillan 1995) - doubles the number of evaluations but better conserves energy

double	accuracyFixedTimestep
	for fixed-timestep integrators, this is the timestep in units of orbital time

double	samplingInterval
	timestep between sampling points for trajectory and other quantities (in units of orbital period)

unsigned int	calcLyapunovMethod
	1 – nearby orbit, 2 – variational equation

unsigned int	numDevVectors
	number of deviation vectors or nearby orbits to compute

double	relaxRate
	magnitude of velocity perturbation term (logLambda/N, with N being the number of discrete stars in galaxy)

bool	freqStrictOrder
	whether to require leading frequencies to be sorted so that w_x <= w_y <= w_z (with small tolerance described below)

double	minFreqX
	search for leading frequency in X coordinate which is not less than MIN_FREQ_X

double	minFreqYZ
	search for leading freq. in Y and Z which are not less than MIN_FREQ_YZ * (leading frequency in X and Y correspondingly)
