Hello!

Here is an update of the progress made during the second week of milestone 1 as part of #SAOC2020.

The main goal set last week was to start working on adding the missing location information to the AST nodes. Here you can find last week's update[1].

What I have done this far:
- Studied the nodes searching for the location information currently present
- Built a list[2] to more easily keep track of the future changes regarding this

Next steps:
- Add the offset from the start of the file to all locations
- Write tests for this change

The initial list of milestones can be found here[3], but will soon be updated to reflect the suggestions received[4].
