a3e7c99ffe ProfileViewer: Add a timeline widget for a visual view of the profile 
Userspace stack frames are in blue, kernel stack frames in red :^)

9150be4716 ProfileViewer: Make sure ProfileNodes have the correct parent pointer 
We were forgetting to call ProfileNode::add_child() which is how the
parent node pointer gets set. This fixes the weird looking GTreeView.

19d8c675f1 ProfileViewer: Begin work on a visualization tool for profiles :^) 
We begin with a simple treeview that shows a recorded profile.
To record and view a profile of a process with <PID>, simply do this:

$ profile <PID> on
... wait while PID does something interesting ...
$ profile <PID> off
$ cat /proc/profile > my-profile.prof
$ ProfileViewer my-profile.prof
