* Update messaging and serialization
* Replace collection prefixes with bigsize instead of u16
* add test vectors
* Use old serialization format for oracle messages
* Add temporary contract id to offer message
* Rename leftEndPoint to endPoint
* Update test vectors
* Fix forgotten types
* Replace bigsize with u64 in payout curve and numeric outcome

* Began work on Numeric Multi-Nonce Outcome spec, wrote compression algorithm
* More progress, specifically on curve serialization and polynomial interpolation
* Separated precision from function points and added note about polynomial evaluation optimizations when precision is not 1
* Wrote section for putting everything together into a CET set computation
* Wrote CET signature validation section
* Filled in all remaining holes!
* Added table of contents
* Added clarification about why base 2 is best, removed some first person
* Added concrete example
* Added subsections to general example
* Added note on non-generality of concrete example
* Clarified optimizations
* Fixed optimizations
* Fixed algorithm typos
* Responded to review, renamed precision_range -> rounding_interval
* Replaced paragraph about accepter's payout_function with new recommendation
* Split NumericOutcome.md into three files and added some design discussion/intentions
* Added extra precision to interpolation points in general payout functions
* Responded to Ben's review
