Issue with DTQP_setup_convert for multiphase

[AzadSaeed]

The way it is currently set up, the conversion code does not enumerate over the length of the new structure, which seems to be needed for multi phase problems. Check case 3 of JadduShimemura for details.

Can you confirm that nonlin.linkage_equality and nonlin.linkage_inequality don't cover the needed fields?
