Highlight files

[pdawyndt]

Add option to manually classify a pair of source files as plagiarism:

• classification : unclassified, plagiarism, innocent
• confidence: scale from 1 (weak evidence) to 5 (strong evidence)
• evidence: free text to describe which evidence has been found

This information could be edited from the compare view (where it is also displayed), and displayed in the list and graph view as for the other metadata on individual files and file pairs. Upon update, the information should also be stored along with the other metadata (CSV file?).

A combination of classification and confidence for a file can be shown as a color (blue/orange) ranging from light to dark. The color of a file could should aggregate the values of the underlying file pairs.

I think we might want to start with the most simple version of this functionality, and expand further if we find there is a need for it.

The simplest start is to be able to "highlight" files. Highlighted files should be quickly accessible and highlighted in every view (graph, list, ...).
