After discussing with @peterbygrave new features will be integrated to IRC. The changes are the following:

• Additional coordinate systems
  • DLC
  • HDLC
  • TRIC
• Additional initial Hessian model(s)
• Constraints

This issue is to track the integration, which will likely involve a refactoring of the library to change name (see Issue #15). There is no precise timeline for this, but priority will be given to additional coordinate systems.
