A brainfuck interpreter for CloudFormation.
This transform looks for a "Brainfuck" key in the provided JSON document. The value of this key should be a string containing a brainfuck program.
The brainfuck will be executed, and any data output (i.e. .) from the program
will be collected to produce a new CloudFormation template. The program should
be capable of producing a complete CloudFormation template in JSON format.
Note: any keys other than "Brainfuck" in the input template will be discarded.
