[Requirements] Bond contract - A bond contract that uses records, with many bonds in the same contract.

[CjHare]

Feature Description

Change the design of the Bond contract; instead of every bond having it's own contract, multiple bonds will use the same contract.

Additional Information

Design wise, switch over to using records for each of the bond with the tokens and assets abstracted (interfaced) away. Initially support a single debt and security asset (in the future there could be multiple securities).
