Add readme and guidelines for SR project

[jarumihooi]

Because

The scene-recognition project contains an empty guidelines.md and an empty README.md. As stated in the repository README file, we want each subdirectory to contain its own README.md detailing annotation project-specific information (e.g. project name, annotator demographics, annotation environment information, gold generation code dependencies, etc.). Each subdirectory should also contain a guidelines.md with relevant annotation guidelines used in the annotation project.

Done when

• The README.md is updated with relevant information.

• The guidelines.md is updated with relevant information.
