Detailed Description

   Structure for equations.  

Field Documentation

int* eqn_d::coef
     Array of coefficients for the equation.  The layout of the data
     is as follows: coef[0] is the constant, coef[i] for 1 <= i <=
     OMEGA_MAX_VARS, are the coefficients for each dimension.  Examples:
     the equation 0 = 9 + x + 0y + 5z is encoded as [9 1 0 5], the
     inequality 0 <= -8 + x + 2y + 3z is encoded as [-8 1 2 3].
