Functions
Functions are special commands that can be run in both chat bots and overlay widgets. Unlike Variables they allow extra options when using them.
The format for a Function is $(functionName [requiredOption] <optionalOption>)
When a Function does not require any options, it can be written simply as $(functionName).
The order of options does not matter, and when a Function uses a "value" option, Variables can also be used (see $(math) for best examples of this).
