add msc_log_to_ladder.py
Add script that reads in an osmo-msc log output and extracts the interesting information for displaying a sequence chart of voice call log, in mscgen format. I want to visualize how the sequence of messages changes across patches. It is error prone to do it manually, and re-doing the sequence chart for every patch (and patch rework) would be prohibitively time consuming. Change-Id: I2e4d8778f7b83dee558517a9b23450b817ee325d

|

Reading a log, it can be hard to figure out what is the important bit going on.
|
||||
This is a tool that reads an osmo-msc log and tries to compose a ladder diagram from it automatically.
