16         Version 6.5 Adjust cms dialog dimensions for Chrome.
17             Version 6.4 Remove fullscreen control. (Use Browser F11 instead).
18         Version 6.3 decomposed into modules for each layer
19         Version 6.2 puts cctv and cms and vds in separate data layers.   
20         Version 6.1 Puts cms messages in json formatted file.  Polls for updates.
21         Version 6.0 Adds speed-dependent images to infowindow for cctv icons
22         Version 5.8 Adds an infowindow with a static image for all cctv icons
23         Version 5.7 integrates CCTV icons and button (but empty click handler)
24         Version 5.6 integrates CMS features
25         Version 5.5 renames title to CPTMS, loads static data on startup and dynamic data
26         every ten seconds. 
27         Version 5.4 adds Search box and Center button
28         Version 5.3 fixed dot color update defect, increased refresh rate to 10 sec.
29         Version 5.2 places red dots overlapping yellow dots.
30         Version 5.1 removes the map and street view buttons and the H3 tag.
31         Version 5 uses precomputed perpendicular vector in dot adjustment function
32         Version 4 Adjust the spacing between dots when the map is zoomed.
33         Version 3 does loadGeoJson only once, and subsequently does an ajax load
34         of the highways file, and selectively updates only those placePins whose
35         color has changed.
