Add java-path-core-maven example
- Contains two sub modules, calculator-input-handler that depends on calculator-operations-provider - java-path-core-maven contains maven-shade-plugin, which provides a runnable jar that packages calculator-input-handler and calculator-operations-provide classes as well as information for main method entrypoint - Add MathOperationsProviderTest in calculator-operations-provider plugin, that is executed during test phase - Logger example in CalculatorInputHandler
