Adding New Semiconductor Patterns

1. In the manufacturer handler's initializePatterns():

Copyregistry.addPattern(ComponentType.MOSFET, "^NEWMOS[0-9].*");
registry.addPattern(ComponentType.MOSFET_MANUFACTURER, "^NEWMOS[0-9].*");

1. Add to getSupportedTypes():

Copytypes.add(ComponentType.MOSFET);
types.add(ComponentType.MOSFET_MANUFACTURER);

Similarity Calculators

• DiodeSimilarityCalculator - Compares voltage, current, type (rectifier/Schottky/Zener)
• TransistorSimilarityCalculator - Compares hFE, Vce, Ic
• MosfetSimilarityCalculator - Compares Vds, Rds(on), Id, package
