[Marketplace] Hypercert collection checkout page

[ryscheng]

Describe the feature you'd like to request

Assuming we implement this first:
hypercerts-org/hypercerts-app#29

It'd be nice to be able to mark a collection for sale.

Describe the solution you'd like

A checkout page that the owner can share publicly.
Users can goto the checkout page and choose what percentage of each hypercert they want to buy.

The checkout process should auto-magically split the hypercerts as necessary and batch transfer to the buyer.

Describe alternatives you've considered

N/A

@Jipperism can you confirm this is possible in the hyperboards app? If so, can you close this issue?

@bitbeckers @holkexyz this is not possible as of now in the hyperboards app. I would say that what is called a collection here, is what we have been calling a registry in the hyperboards terminology.

A few issues with this that we'd have to think through: a registry is a collection of claims, whereas the unit that is actually being put on sale is a fraction. This would require some logic to determine which parts of a hypercert could be put on sale. Would that be all the fractions, within this collection of hypercerts that are owned by the person putting them on sale? Would it only be applicable to collections of hypercerts that all consist of a single fraction, all owned by the person putting them on sale?

Seems like this feature needs quite a bit of refinement and is blocked until we now what exactly constitutes a collection.
