/**
* A helper class for accessing properties in nested objects, e.g., accessing
* the "getRidge" method of a LinearRegression classifier part of
* MultipleClassifierCombiner, e.g., Vote. For doing so, one needs to
* supply the object to work on and a property path. The property path is a
* dot delimited path of property names ("getFoo()" and "setFoo(int)" have
* "foo" as property name), indices of arrays are 0-based. E.g.: <p/>
*
* <code>getPropertyDescriptor(vote, "classifiers[1].ridge")</code> will return
* the second classifier (which should be our LinearRegression) of the given
* Vote meta-classifier and there the property descriptor of the "ridge"
* property. <code>getValue(...)</code> will return the actual value of the
* ridge parameter and <code>setValue(...)</code> will set it.
