QR Code commands/rules

New subcatalog command can be:
*S                 create new subevent with default # of digits
*Sn                create new subevent with n digits (where n >= 1 && n <= 9)  e.g. *S4 ->  0001
*S=###             create new subevent with 3 digits e.g. 001
*S=mysub          create new or reuse subevent always named "mysub"
*S=mysub###       create new unique subevent mysub001

• format of data in EXIF Comment field should be:   Name=John Doe;Age=25 
• field/variable name followed by equal sign and value.  use semi-colon to separate multiple Field=Value pairs.
• there's no limit on the # of fields, but using too many will make QR Codes too dense and harder to scan
• In templates, you can use this data in two ways:
• Just use regular template text variables like %Name% and %Age% and the fields will be defaulted to the values from the User Comment
• or, you can use %UserComment.field%  (e.g. %UserComment.Name%).  This will do the same thing BUT will always use the data from the EXIF comment without ability to edit via the Template Text field edit dialog
• switching between images which contain data fields in the EXIF Comments will automatically change template text displayed on screen

While viewing an image's Properties on Library and Workshop page, you can now double click the EXIF Comment to edit it.  You can put in any text including variables as described above.

Random Code Generation

You can surround in percent signs as border variables %RANDOM% or {RANDOM} but the simple cases above do not require that.

Note* It is suggested that you generate at least 6 digits of random data.  The software will try to guarantee unique IDs are generated within one catalog, but using more random digits is best.
