Problem: In order to provide proper entrypoint calling description Lorentz contracts use finalizeParamCallingDoc function. However, Indigo currently doesn't have an analogue for finalizeParamCallingDoc. As a consequence, autodoc for Indigo contract isn't proper.

Solution: Add Indigo finalizeParamCallingDoc version.
