Public Attributes
Run time parameters
double	gamma
double	reference_density
double	vacuum_state_relaxation_small
double	vacuum_state_relaxation_large
Cached inverses
A collection of commonly used expressions with gamma that would otherwise need to be recomputed many times putting unnecessary pressure on the div/sqrt ALU unit. These are recomputed in update_parameters().

Detailed Description

A structure holding all runtime parameters of the hyperbolic system, as well as a number of derived quantities that would otherwise need to be recomputed over and over again.
