Quiz example project

This Pull request addresses the issue: #3327

I added a html file crossword-puzzle.html which runs a crossword puzzle game as described. Based on instructions from @pikurasa , this is based off https://musicblocks.sugarlabs.org/index.html?id=1699191323362045&run=True that nice framework which uses a heap to store characters of answers.
So, changing or creating new quizzes are as simple (just change word characters from answer - action_block and change question text, answer variable, hint text and word length from 'setQaHeap' - action block ) instructions are also included in a action block named 'doc'

I really had fun learning new music concepts and working with musicblocks. This is my first real-world opensource contribution, so if you would like to share some suggestions/ areas of improvement, I am happy to learn

@pikurasa could you kindly review this

I'll check it out soon.

It works well.

Two points of quick feedback:

• I'd much rather avoid the "deaf" question on these quizzes; please find another question to do there instead
• When it plays back the pitches, it currently plays them back backwards; you may need to use "reverse heap" block, but please have the playback perform the pitches in the correct order

@pikurasa Sorry, I didnt notice them properly

I used a counter variable and index heap block to resolve that issue
now the pitches are played in the correct order

I have made the required changes and double checked them for any issues

This version works well. But since it is a quiz, not a crossword, the file name should be updated?

[pikurasa]

@walterbender I tested it and I think we could merge it into examples now.

I could think of some improvements, but I think this is a great start.

Do you have additional feedback?

Oh yes; agreed.
