Detailed Description

An abstract Source that creates some Graph in the background.

Subclasses usually fetches some data from web and parses it to some Graph for visualisation.

An useful skeleton is the SourceRegExp which uses a regular expression to do so.

Finding Sources by given url

the given URL is evaluated for source=... query and a Source of apropriate class is instantiated.

If no matching class is found, null is returned.

If a matching class is found, but the factory constructor signature (URL) is not found, an exception "Source: No valid public constructor at class CLASS" is thrown to encourage the implementation of an apropriate constructor.
