Organize baselines

Currently I have tons of baselines. Would be nice to have some sort of hierarchical way of organizing them.

For instance, would be nice to have a menu like this:

• Siamese with BN
  • Baseline 1
  • Baseline 2
  • Baseline 3
• Siamese with BN only bias
  • Baseline 1
  • Baseline 2
  • Baseline 3
• Triplet with BN
  • Baseline 1
  • Baseline 2
  • Baseline 3
• Triplet with BN only bias
  • Baseline 1
  • Baseline 2
  • Baseline 3
