SPSE Module 4. Lesson 7. Ex.1
Web Spider.
So far it reads links and HTML but recursivity is not working correctly
I think it's because I'm modifying a list while reading it...

ToDo: Fix it
Second version:
Instead of using a number for representing the maximum depth the crawler should go
I'm using a number to represent the maximumm number of links the crawler should visit.

That changed the logic of the program and made it easier. Recursiveness is working fine

ToDo: Connect to a MySQL DB and write results to it
