A hierarchy of software components is created based on the programming constructs therein using a computer linked to a database having a collection of legacy software therein. According to one aspect of the disclosure, a method is provided including identifying a preignition event at an affected cylinder; deactivating the affected cylinder during a deactivation period; initiating an accommodation system for one or more unaffected cylinders; and activating an indicator system. The electrolyzer of the present invention comprises one or more supplemental electrode at least partially immersed in an aqueous electrolyte solution interposed between two principle electrodes. The method further includes the displaying of a finder field on the display adjacent to the plurality of navigation nodes in the graphical navigation string for searching the first level of the navigation hierarchy.
