Facilities to reduce abuse of _attached_cfrags #249

Closed jMyles closed 5 years ago

jMyles commented 5 years ago

Presently, there are several places in the NuCypher codebase (and on in this codebase) where we abuse the private _attached_cfrags attribute of Capsule.

This PR allows for the Capsule's CFrags to be cleared without needing to access this attribute.

Unrelated to the PR itself, but failing CI seems do be looking for import sha3?
