From e0b32856c0938d4e81262a55eb0ce42344e4e6b6 Mon Sep 17 00:00:00 2001
From: Lewin Probst <info@emirror.de>
Date: Wed, 2 Oct 2019 13:07:47 +0200
Subject: [PATCH] Time of arrival window update.

+ Added soundsources/colorregister package that is used to assign a color
  to a specific sound source.
+ Added an edit field to the upper and lower boundary adjustment section
+ Added a histogram plot of the TOAs
/ The soundsource color legend shows only the color of an applied sound
  source, white otherwise.
