Refactor Lecture TWP42: Bases de datos (indexedDB approach)

[AngelaRemolina]

Summary

This PR may close: AngelaRemolina#48
I have implemented an approach to solve this issue of lecture TWP 42: Bases de datos with an API that is supported by Brython called indexedDB.

Important note: The refactoring is not finished, this is just a test. Even though this is a functional solution, the syntax changes a lot from the original lecture where sqlite3 was used.

For example:

cursor.execute("select * from surfers  where age > 25")
linhas = cursor.fetchall()
for linha in linhas:
    print("id :",linha['id'])
    print("Nombre :",linha['name'])
    print("Pais  :",linha['country'])
    print("Media  :",linha['average'])
    print("Estilo :",linha['board'])
    print("Edad  :",linha['age'])
    print()

had to change to:

if(getattr(v, "edad") >=25):
    for key in ["nombre", "pais", "media", "estilo", "edad"]:
        print(f"{key}: {getattr(v, key)}")
  getattr(res, "continue")()

I will keep exploring other possible options, but this is a starting point in case none other option is found.
