feat: Complete relational functions for vectors

Browse source 
Toward its goal, this commit also:
  * Adds a new section of logical functions, and defines `not`, `and`,
    `or` for all current types.
  * Extends `OneOf` choice/union type to allow argument types that are
    themselves `OneOf` types.
  * Adds a readable .toString() method for TypePatterns.
  * Defines negate (as a no-op) and isnan (as always true) for the Undefined
    type
  * Extends comparisons to the Undefined type (to handle comparing vectors
    of different lengths)
