Class Heatmaps / Class Reorg. Plots buttons

[dweindl]

@DTSHaas : So far, these buttons are hidden:

C-COMPASS/src/ccompass/main_gui.py

Lines 971 to 988 in f3ed5a8

	[
	sg.Button(
	"Class Heatmaps",
	size=(15, 1),
	key="-class_heatmap-",
	disabled=True,
	enable_events=True,
	visible=False,
	),
	sg.Button(
	"Class Reorg. Plots",
	size=(15, 1),
	key="-class_reorganization-",
	disabled=True,
	enable_events=True,
	visible=False,
	),
	],

Should they be rendered functional, or was that just for testing purposes and should be removed?

These buttons were disabled since the plots that are planned to be displayed here should be approved by the paper's reviewers before we implement them. Buttons could be removed ore stored for a later version.
