[AngelaRemolina]

Summary

This PR may close: AngelaRemolina#48
I have implemented another approach (better than tha one on this PR to refacto this lecture.
I use sql.js library for SQLite compiled to JavaScript. I load create the original surfersDB from the PyZombis course using the .. raw:: html tag as a global variable.

I'm still working on accessing this global variable from the activecode block with Brython. But I can confirm the db is global since in the browser console you can print it (see image below)

Hi @angelasofiaremolinagutierrez , based on your PR i made some changes in ..raw:: html tag and now we can access the sql.js db using document module provide by activecode. Have a look at this PR #200 . I think we can use this to move forward with the lectures. Let me know what you think.
