add file showing code for review

[kweav]

Specifically just adding an Rmd and its rendered html showing the code/steps I used

The two file paths that will need to be changed/updated if you want to run it are

• the RDS file (line 17). I used the results folder that you sent me when I started working on this project and wanted to compare results from gimap with the GI mapping results.
• line 253, I had to provide the annotation file as described earlier. I used a relative local path and not the here package, so it would just have to be updated as well

In the ### Get the gimap data setup, I used the code from the getting-started.Rmd vignette, but I know that can be simplified by running get_example_data('gimap') instead. I'm fairly certain I did both yesterday. I just had this block in my scratch notes.

Did some minor changes to this that don't chnage the results but just reduce the amount of code. Going to merge this!
