no_gen keyword at the controller level turns off all generation of the controller and its methods.
Use this when you've been very naughty and modified the GEN module to avoid having Bigtop overwrite your changes,
or when you are overwhelmed with paranoia.
Note that the value of this statement must be true. I usually use 1 as the value.
When you try to build the example with:
bigtop -c example.bigtop all
bigtop will create everything as normal except make the stub/GEN pair for the Child controller.
