Census of covering of strata

[videlec]

Similar to OrigamiDatabase it would be desirable to have a more general census of covering of connected components of strata. The main questions are

• use Calderon-Salter : they prove that twists in an appropriate ThurstonVeech surface generates the monodromy group
• how do we represent the data internally? In particular, there should be a way given a IETPermutationCover to recover the associated covering
• user interface?
