Parallel screening phases

[esyriani]

Currently, if I have 3 screening phases P1->P2->P3 in this order, then the papers included from P1 and transferred to P2. The included papers from P2 are transferred to P3. This is a sequential pipeline of screening phases.

We want to introduce the concept of parallel phases, like P1+P2->P3. This means that the papers included from P1 and P2 are transferred to P3, but P1 and P2 do not share the same articles. This way, we can have separate statistics for each phase.

This means we need to enhance ReLiS with the following features:

• Assign papers to a phase
• Define the next phase of each phase. If no next phase, then it is final before going to QA or classification. Exactly 1 phase must be final.
• Define the assignment of papers to reviewers (users and number) to be fixed for each phase.
