 Quaff.Debug
 -----------
 
 The Debug module provides a simple helper interface for running Elixir code in the erlang graphical debugger, using the technique I described in [this posting](http://qhool.github.io/elixir/2014/02/06/elixir-debug.html).

-    Interactive Elixir (0.12.2) - press Ctrl+C to exit (type h() ENTER for help)
-    iex(1)>  Quaff.Debug.start() #start the graphical debugger
-    {:ok, #PID<0.59.0>}
-    iex(2)>  Quaff.Debug.load("./lib/mymodule.ex") #load all modules in source file
-    lib/mymodule.ex:1: redefining module My.Module
-    lib/mymodule.ex:212: redefining module My.OtherModule
-    [module: My.Module, module: My.OtherModule]
-    iex(3)>  Quaff.Debug.load(Yet.AnotherModule) #load a module by name
-    {:module, Yet.AnotherModule}

 Also provided is `nload(module)` (equivalent to `load(module, all_nodes: true)`), which debugs the module[s] on all known nodes.
