Hello!

From now on I will use this thread to post updates on this project, so that they will be easier to follow.

The progress made so far:
Milestones: [1]
Milestone 1 Week 1: [2]
Milestone 2 Week 2: [3]

#SAOC2020 Milestone 1 Week 3

This week I planned to add the buffer offset to the token location.

What I have done:
- Added the extra field to the location under a version so that the usual performance wouldn't be hurt and this information will only be available when requested [4]
- Wrote some tests for this change but more would need to be added
- Changed the newScope visitor into a switch [5]

Next steps:
- Add the missing tests for the buffer offset [6]
- Add the token size
- Bring all DMD as a library additions hidden behind a version under the same one
- Add the start location to the nodes that lack this information
