invoke the calculation of all node weights according to a focus node that is passed to the function as an adress value specifying its index in the allNodes LinkedList
This class receives several user input options: the tag that is used for nodes, the unique ID attribute and the tag used for crossRefs
It invokes the configuration Parser that parses, if available, the config part of the xml source file (that has a predefined grammar) and
stores the config values to so called config sets, which can either be of type RangeConfigSet (representing a direct value range which can be use for node sizes)
or of type SwitchConfigSet that can be used for colors as well as for size categories.
This class hold a collections of colors and is able to map an integer color attribute to a java.awt.Color
The colors are used in association with connections, so no very light colors are used.
A ConnectionTypesSet is a data structure that holds all available types of connections
as a list of connectionNames (the names that are used as the attribute value of
tags.
A simple XML parser to transform XML input into da 2D adjacence matrix and prepare a list of nodes and node ids
Furthermode, a tree model for the content JTree is initialised based upon the source.
