VIS: added orderId for singles on metricvisualizers
VIS: fixed a bug with coloring in ms-vis configs
VIS: added orderId for singles on ms-visualizers
VIS: removed debug log output
VIS: added dynamic scrollpane to statsgroups

- All statsgroups have a JScrollPane in which its stats are being shown
- ScrollPane scales dynamically with amount of values, up to a maximum
height threshold of 100 (hardcoded, can be changed in StatsGroup.java)
- Default-Config & displayConfig adjusted accordingly to adapt to the
now a bit wider statsgroups
VIS: fixed a size-issue with statsgrp scrollpanes

Issue occured when only one value was being added to the statsgroup,
causing in an unintended height, which showed the vertical scrollbar.
VIS: removed debug messages from last commit
VIS: added lock checkboxes to GUI

- Each visualizer has a chekbox in his legend, allowing to separately
lock the visualizer, preventing any alteration on the values in the
legend due to resets (pressing the Stop-Button) and / or directory
changes.
- A mainlnock was added to the main display, which can be used to
select/deselect the checkboxes of all visualizers.
VIS: fixed a bug with timeslider with zip batches

Bug was caused when timeslider was moved or the timeslider-buttons where
being used. In that case zipped batches was not being considered and the
normal read operation was executed, resulting in a file not found
exception.
GEN: Added BatchReadMode for BatchData objects
GEN: BatchReadMode added to plotRun-Methods
IO: metrics w/o values will no longer create file
PLOT: added PlottingUtils class
PLOT: moved additional methods to PlottingUtils
Updated Assortativity to match new metric types. Aggregated all nine
classes to only three. Use AssortativityU or AssortativityR for all
types of graphs (weighted, unweighted, directed, undirected) and set
details by parameters from now on.
Assortativity: replaced StringParameters in constructor and computation
methods by enums to prevent illegal values.
Updated Similarity Measures to match new metric types. Combined all
classes for Matching Similarity in only three.
