/** @short factory to create detect service objects and initialize it in the right way.

@descr This class can be used to create new detect services for specified contents.
|
|
It uses cached values of the configuration to lay down, which detector match
|
|
a given name. Further this class provides full access to the configuration data
|
|
of such detect services and following implementations will support some special
|
|
query modes.
