/**
 * The TokenCoverageChecker performs two diagnostics to detect parser bugs:
 * 1. It checks for two DocNode objects whose excerpt contains overlapping tokens.
 *    By design, a single character from the input stream should be associated with
 *    at most one TokenSequence.
 * 2. It checks for gaps, i.e. input tokens that were not associated with any DocNode
 *    (that is reachable from the final DocCommon node tree).  In some cases this is
 *    okay.  For example, if `@public` appears twice inside a comment, the second
 *    redundant instance is ignored.  But in general we want to track the gaps in the
 *    unit test snapshots to ensure in general that every input character is associated
 *    with an excerpt for a DocNode.
