Finds all mentions of functions in z_sub_s in code. Can easily modify it to look at overlays or other directories, and use other files, and makes graphviz-compatible output

# TODO
# - take arguments for callee functions directory and sought callers rather than 
# - maybe pass straight to graphviz with | dot -Tsvg > name.svg
# - or | dot -Tpng > name.png
# - implement colours for jal/hilo (functionality currently unused)
