Functor 2.0

[baetheus]

Standard Module Implementation for functor.ts

• Add file block comment at top of file describing the adt/structure.
• Check for any missing combinators/derivations that could be implemented.
• Modify all combinator variable names to be readable (use style guide).
• Add documentation to every export (and // comment local tools).
• Check that every function and line is covered by tests in the testing directory.

Style Guide

• Use A -> I, B -> J, C -> K, D -> L for inner types.
• Use ua, va to match URI, VRI, etc in generic positions.
• Implement algebraic structure types (type classes) out to length 4.
• Use functions over const arrow functions for root exports.
• Document all type exports.
• Order file exports by group and then alphabetically. Groups are Types, Constructors, Combinators, Type Class Instances, Type Class Constructors, and Derived Combinators.

Documentation Guide

• Start with at least one full sentence describing the use case for the export.
• Include a @SInCE tag (default to 2.0.0)
• Include an @example tag with a simple example
  • Imports should be relative for functional stuff and otherwise full urls with versions
  • Example should end with at least one assert from the deno std lib
