c429c19dfe feat: Implement subtypes
This should eventually be moved into typed-function itself, but for
  now it can be implemented on top of the existing typed-function.

  Uses subtypes to define (and error-check) gcd and lcm, which are only
  defined for integer arguments.

d9d7af961f refactor: Simpler merging mechanism
Merging of Pocomath modules is eased by allowing one PocomathInstance to
  be merged into another. That allows types, for example, to be exported
  as a PocomathInstance (so there is no need for a special identifier
  convention for types; they can be directly added with an installType
  method). Also, larger modules can just be exported as an instance, since
  there is more flexibility and more checking in merging PocomathInstances
  than raw modules.

f68c7bd1fb fix(Types): Move distinct types into distinct identifiers
This allows types to be collected; prior to this commit they
   were conflicting from different modules.

   Uses this fix to extend sqrt to bigint, with the convention
   that it is undefined for non-perfect squares when 'predictable'
   is false and is the "best" approximation to the square root when
   'predictable' is true. Furthermore, for negative bigints, you might
   get a Gaussian integer when predictable is false; or you will just get
   your argument back when 'predictable' is true because what other
   bigint could you give back for a negative bigint?

   Also had to modify tests on the sign in sqrt(Complex) and add functions
   'zero' and 'one' to get types to match, as expected in .

   Adds numerous tests.

91ec20edd8 feat: Implement signature-specifc reference
Also implements a config object that upon change, lazily invalidates
  all operations that access it.

  Also allows references to signatures with nonexistent types (which
  typed-function does not); they come back as undefined.

  Uses these features to implement sqrt for number and complex.

9fb3aa2959 feat: Switch to function-based specification of dependencies
Allows dependencies to be economically expressed and used.
  For example, see the new definition of subtract.

0069597a76 fix: Separate typed instance for each PocomathInstance ()
Also starts each PocomathInstance with no types at all, and uses the new
  situation to eliminate the need for a Complex "base case".

84a8b9d5c4 feat: Allow self-reference in implementations ()
This PR also uses such self-reference to define negate and add
  for Complex numbers in a way that is independent of component types.

  Also adds a bigint type and verifies that pocomath will then handle
  Gaussian integers "for free".

  Ensures that if one function is invalidated, then any that depend on it will be.
