/*
* This class is used to provide help
* to the operator.
*
* Help is provided by a momentary push button on the window. When first
* clicked a search index is set to 0. Tile searches are performed by searching
* from the current search index to the end of the tile list. If a match isn't
* found the index is incremented and the scan starts anew until either a match
* is found or all tiles have been exhausted. When a match is found the two tiles
* are highlighted.
