* Propagates {@code throwable} as-is if it is an instance of {@link RuntimeException} or {@link
* Error}, or else as a last resort, wraps it in a {@code DroidDriverException} and then
* propagates. <p> This method always throws an exception. The {@code DroidDriverException} return
* type is only for client code to make Java type system happy in case a return value is required
* by the enclosing method. Example usage:
* <pre>
* T doSomething() {
* try {
* return someMethodThatCouldThrowAnything();
* } catch (IKnowWhatToDoWithThisException e) {
* return handle(e);
* } catch (Throwable t) {
* throw DroidDriverException.propagate(t);
* }
* }
* </pre>
*
* @param throwable the Throwable to propagate
* @return nothing will ever be returned; this return type is only for your convenience, as
* illustrated in the example above
