-/**
- * Contains {@link Source} and location information for AST nodes.
- * <p>
- * Each node in the subtree (other than the contrived nodes) carries source range(s) information
- * relating back to positions in the given source (the given source itself is not remembered with
- * the AST). The source range usually begins at the first character of the first token corresponding
- * to the node; leading whitespace and comments are <b>not</b> included. The source range usually
- * extends through the last character of the last token corresponding to the node; trailing
- * whitespace and comments are <b>not</b> included. There are a handful of exceptions (including the
- * various body declarations). Source ranges nest properly: the source range for a child is always
- * within the source range of its parent, and the source ranges of sibling nodes never overlap.
