  * The cached lookup-table to associate doc comments with spans. The outer map
  * is from filenames to doc comments in that file. The inner map maps from the
  * token positions to doc comments. Each position is the starting offset of the
  * next non-comment token *following* the doc comment. For example, the position
  * for this comment would be the position of the "class" token below.
