Portable abstractions and patterns for Pip.Services in Node.js

/**
 * Helper class to perform method introspection and dynamic invocation.
 *
 * This class has symmetric implementation across all languages supported
 * by Pip.Services toolkit and used to support dynamic data processing.
 *
 * Because all languages have different casing and case sensitivity rules,
 * this MethodReflector treats all method names as case insensitive.
 *
 * ### Example ###
 *
 *     let myObj = new MyObject();
 *
 *     let methods = MethodReflector.getMethodNames();
 *     MethodReflector.hasMethod(myObj, "myMethod");
 *     MethodReflector.invokeMethod(myObj, "myMethod", 123);
