[story645]

• [x] pull out args, kwargs where the possible, - can't, blows up spectacularly
• [x] encoder(view[f] if f is not None else None), to be super strict on getting the key,
• [x] err on the side of being super strict - will break things badly
• [ ] if keys are 0,1,2,3 this model will do the right thing
• [x] pull out bar to top (use scatter dataset for the bar since same topologies)
• [ ] refactor multibar into seperated Q and make use of bar more
• [x] rewrite Qhat paragraph, handwave to why we don't do anything w/ rho
• [x] pull punchline from math into here - assemble is Q which gives X
• [ ] assume reader for this section has skimmed math
• [ ] how this functionality can be exploited for their purposes
• [x] replace FiberBundle w/ data class?
• [ ] line is assuming that we do linear interpolation on the interval - Line artist draws as linear interpolation on the segments
• [x] view (takes an axes argument) is how we do sheafs or jets/restricting before we come in
• [x] validation is not shown for clarity but would be implemented as part of validation
• [ ] makes clear what the extension points are
