; :Keywords:
; color: in, optional, type=varies
; Set this keyword to the color (color table index, 24-bit value, or color name)
; of the color desired.
; names: in, optional, type=boolean, default=0
; If this keyword is set, the function returns the names of the symbols allowed.
; The index number of the name is its symbol number.
; thick: in, optional, type=float, default=1.0
; Set this keyword to the thickness desired. Default is 1.
;
; :Examples:
;
; To use with normal IDL routines::
; Plot, findgen(11), PSYM=cgSymCat(theSymbol)
;
; To connect symbols with lines, use a negative value for the PSYM keyword::
; Plot, findgen(11), PSYM=-cgSymCat(theSymbol)
;
; To use with Coyote Library routines, you can call cgSymCat indirectly::
; cgPlot, findgne(11), PSYM=16, SYMCOLOR='dodger blue'

; :History:
; Change History::
; Written by David W. Fanning, 2 September 2006. Loosely based on the
; program MC_SYMBOL introduced on the IDL newsgroup 1 September 2006,
; and MPI_PLOTCONFIG__DEFINE from the Coyote Library.
; Modified to allow PSYM=8 and PSYM=10 to have their normal meanings. This shifted
; previous symbols by two values from their old meanings. For example, an hourglass
; went from symbol number 19 to 21. 2 October 2006. DWF.
; Whoops! Added two symbols but forgot to change limits to allow for them. 4 May 2007. DWF.
; Added THICK keyword. 21 Aug 2007. DWF.
; Added COLOR keyword and made THICK keyword apply to all symbols. 11 Nov 2008. DWF.
; If you are using USERSYM, the "color" can get "stuck" on the last color used to draw
; a symbol. To "unstick" the color, you have to call USERSYM without a color keyword
; before calling it again with a color keyword. This is, without a doubt, the strangest
; bug I've ever seen in IDL! 20 June 2012. DWF.
; Changed the way I "unstick" the color from calling USERSYM to calling SYMCAT. This
; avoids a problem in changing the symbol when SYMCAT is used (unnecessarily) to pass
; a symbol into Coyote Graphics programs. 9 July 2012. DWF.
; Added the ability (via Jack Saba) to ask for symbols by name. 17 July 2012. DWF.
; Added the ability to ask for the color by name. 17 July 2012. DWF.
; Renamed to cgSYMCAT from SYMCAT. 17 July 2012. DWF.
; The previous problem with USERSYM colors "sticking" turned out to be a problem
; with cgGraphicsKeywords, so I removed previous "fix". 18 July 2012. DWF.
; Modified the program to allow a "negative" string to be used as the symbol name
; (e.g., PSYM="-star"). 30 July 2012. DWF.
; Modified to use 36 points in circle, rather than 72. 10 May 2013. DWF.
; Fixed a problem with using parentheses, rather than square brackets. 15 Dec 2014. DWF.
