RxJavaExamples

Several simple examples demonstrating how to use RxJava along with a few exercises to try as seen in the comments. All code here are simple Java examples wrapped up so you can try them in Android Studio's console.

     * Use this online documentation:
     *  https://github.com/ReactiveX/RxJava/wiki/Filtering-Observables
     *
     * Try the following Rx tricks:
     *
     *  1. takeLast() the last 2 results.
     *  2. elementAt() to obtain value #567.
     *  3. take() the first 10 results.
     *  4. Do #3 and also filter() only values divisible by two.
     *
     *      Keep in mind that order of operations matters!
     *      Use bigInteger.mod(BigInteger.valueOf(2)).equals(BigInteger.ZERO) to test for even values.
     *
     * Use this online documentation:
     *  https://github.com/ReactiveX/RxJava/wiki/Transforming-Observables
     *
     *  5. Use map() to convert from BigInteger values to Long values and take only the first 50 results.
