The built-in repair functions.

A repair fn must take a HGVS string and an inferred kind, and return a
repaired HGVS string. e.g.

  (defn lower-case-ext
    [s kind]
    (if (= kind :protein)
      (clojure.string/replace s #"EXT" "ext")
      s))

The built-in rules are based on frequent mistakes in popular public-domain
databases such as dbSNP and ClinVar.

Infers a kind from the provided string, returning the kind keyword.
