To do list
* p-adics
#8685: evaluation of Monsky-Washnitzer objects (really about power series over p-adics)
#11319: Cannot create homomorphism from prime residue field to finite field
* computing with chi_18
* wrapping of gauss composition (in pari: QuadClassUnit)
* #11697: Global minimal models over number fields with class number >= 1
- this is in Connell and probably wouldn't take to long to get at least a python toy version
- Sage already has this for class number 1 fields
* Reviewing number theory and elliptic curve tickets
