How to see function calls? #116

Open SimonLab opened 5 years ago

When debuging a function it's often helpful to have a log of all the functions that are being called when running a specific functions. At the moment I'm using a lot of IO.inspect which is good but tedious when a lot of functions are called.

I think the dbg module of Erlang can be used to trace the function calls: http://erlang.org/doc/man/dbg.html
