/**
 * The CommentRange entity describes the range of an inline comment.

 *
 * The range includes all characters from the start position, specified by
 * start_line and start_character, to the end position, specified by end_line
 * and end_character. The start position is inclusive and the end position is
 * exclusive.
 *
 * So, a range over part of a line will have start_line equal to end_line;
 * however a range with end_line set to 5 and end_character equal to 0 will not
 * include any characters on line 5.
