loadEstimates.lavaan.ordered

Not generally intended to be used on its own, but exported anyway for
didactic purposes.

Allows for multiple group item response theory alignment a la 'Mplus' to be applied to lists of single-group models estimated in 'lavaan' or 'mirt'. Allows item sets that are overlapping but not identical, facilitating alignment in secondary data analysis where not all items may be shared across assessments.
