 - Refactor graph helper functions from `app/Svg/Database.hs` to `app/Models/Graph.hs`
 - Refactor functions for performing matrix operations from `app/Svg/Parser.hs` to `app/Util/Matrix.hs`
 - Updated documentation in `app/Util/Blaze.hs`
+- Moved the `Course` data type from `Database/Tables.hs` into `Models/Course.hs`, renamed it to `CourseData`
 - Removed `SvgJSON` data type in favour of `([Text], [Shape], [Path])`
