- make them into jupytxt notebooks
- relocate agentgraft.jl from bin to examples

this reporting code prints tables to show
how to compare models with agentmodels.

drop qualified usage from the example bin/agentgraft.jl

this is a really weird way to program.

this version makes takes a shot at what graft.jl would look like
if all the code generation of the new model happened in the library
the API needs to be polished before this would be considered useful.

include more functionality from MacroTools.jl into src/macrotools.jl
include more functions for working with ASTs such as

- callsites: for finding the uses of a function
- structured: for capturing the structuring and destructuring assignments

graft.jl is now pretty well refined

unifies example threaded throughout
