MultirationalMap <==> MultirationalMap -- equality of multi-rational maps with checks on internal data

• Operator: <==>

• Usage:

  Phi <==> Psi

• Inputs:
  • Phi, a multi-rational map
  • Psi, a multi-rational map
• Outputs:
  • a Boolean value, whether Phi and Psi are the same multi-rational map, by throwing an error if an inconsistency of the internal data is detected.
