#  DESCRIPTION:
#                   Add a iconbutton in maya script editor, to print
#                   the value of selected Mel variable.
#                   Feel free to use this codes,Dont be hesitated to
#                   give me any suggestion or bug report.
#               
#                   For a convenient single-file release,I converted
#                   the icon to base64
#                   encoding schemes, use following method to convert
#                   your icon:
#
#                   imgfile = file(r"C:\_StarportX.Software\Mel\icons\base1.png","r").read()
#                   base64code = base64.b64encode(imgfile)
#                   print base64code
#                   replace the base64code in the code.
#
#   USAGE:        Put this file in "C:\Users\(XXX)\Documents\maya\(maya-version)\scripts"
#                     import printMelVar
#                     printMelVar.makePrintVarBtn() # add button
#                     printMelVar.delPrintVarBtn()  # delete button
#                     printMelVar.PrintSelVar() # bind this cmd to a hotkey gonna be better
