Determine which format handler to use for a source file. If the source file is DSML then {@link #dsmlFormatHandler}
will be used and if it is LDIF then {@link #ldifFormatHandler}.

@param source Describes the source file.
@return The appropriate format handler or {@code null} if the source is not supported.
Determine which format handler to use for a source file . If the source file is DSML then { @link #dsmlFormatHandler } will be used and if it is LDIF then { @link #ldifFormatHandler } .
