Functions

`core_mask`(R, Z, psi, opoint[, xpoint, psi_bndry])	Mark the parts of the domain which are in the core
`find_critical`(R, Z, psi[, discard_xpoints])	Find critical points
`find_psisurface`(eq, psifunc, r0, z0, r1, z1)	eq - Equilibrium object (r0,z0) - Start location inside separatrix (r1,z1) - Location outside separatrix
