Do not enable this file, this is simply to document how you can access nested lists and how to generate key lists from a key:value pair.

+Nested lists are lists within lists, now this was probably obvious, i wouldnt waste your time with this.
+What we are going to be talking about is Nested lists with key value pairs and how to access them as well as generate key lists
+
+These are incrdeibly nice for merging multiple lists with a similiar purpose. this example here will write a fake implementation to unify the Robot_module list.
