* This FilterManager is resposible for the conversion of the different
* molFileFormats (ways of storing molData) into useful objects.
* The real work (read/write) is done by single filters that are known here.
*
* For interface-info see the header file. The comments in this file mostly
* cover only the real implementation details.

/*
* History: 30.10.94 Switched to the MiscString.
*
* 15.03.94 Added MvtxFilter and AlchemyFilter.
*
* 14.03.94 Made it a real manager. It now will handle different
* filetypes.
*
* 14.01.94 Made the parsing somewhat nicer and cleaner.
*
* 13.01.94 Did completely rewrite the parsing section. Now uses
* MOStrings to parse self.
*
* 28.12.93 Created a initBeaker method.
*
*
* Notes: - Once we have some more filters that can only MAYBE handle a
* file we will have to bring up a panel that lets the user choose
* the filter he wants.
*
*
* Bugs: - No removal of filters.
*
* - Because this object might someday be used by different beakers at
* the same time I should add some locking or what ever. Right
* this is no problem at all.
