                       File Association
_____________________________________________________________________________

 Based on code taken from http://nsis.sourceforge.net/File_Association 

 Usage in script:
 1. !include "FileAssociation.nsh"
 2. [Section|Function]
      ${FileAssociationFunction} "Param1" "Param2" "..." $var
    [SectionEnd|FunctionEnd]

 FileAssociationFunction=[RegisterExtension|UnRegisterExtension]

_____________________________________________________________________________

 ${RegisterExtension} "[executable]" "[extension]" "[description]"

"[executable]"     ; executable which opens the file format
                   ;
"[extension]"      ; extension, which represents the file format to open
                   ;
"[description]"    ; description for the extension. This will be display in Windows Explorer.
                   ;


 ${UnRegisterExtension} "[extension]" "[description]"

"[extension]"      ; extension, which represents the file format to open
                   ;
"[description]"    ; description for the extension. This will be display in Windows Explorer.
