 * This class is the interface that all IO readers should implement.
 * Programs need only care about this interface for any kind of IO.
 * Currently, database IO and file IO is supported.
 * <p>The easiest way to implement a new ChemObjectReader is to
 * subclass the DefaultChemObjectReader.
 * <p>I don't know how this should be enforced, but a Reader should
 * also provide an empty constructor so that ClassLoader/getInstance()
 * can be used to instantiate a ChemObjectReader.

     * Reads an IChemObject of type "object" from input. The constructor
     * of the actual implementation may take a Reader as input to get
     * a very flexible reader that can read from string, files, etc.
     * @param  object    the type of object to return
     * @return returns an object of that contains the content (or 
     *         part) of the input content
     * @exception CDKException it is thrown if
     *            the type of information is not available from 
     *            the input
