allow custom node-IDs during tree-import

[westram]

Need a possibility to import trees that use alternative IDs at leafs, e.g. 'acc' and/or 'start'/'stop' positions etc.

Possible implementation:

• provide importer with 2 ACI expressions:
  • 1st expression creates a unique ID from every leaf ID found in imported
    • if not specified ⇒ use ID as found in
  • 2nd expression creates a unique ID from every species existing in the
    • if not specified ⇒ use 'name' field as ID
• test that all IDs generated by one expression are unique! (or bail out)
• map leafs of imported to species
  1. wherever both generated IDs match or (alternatively)
  2. one ID is contained in other ID.
• create zombies and warn on mismatch.

The method described above can be applied

• to all leaf labels of imported or
• to all zombie labels of any existing .

Notes:

• allow to define ACI expressions via import GUI
• allow to specify ACI expressions via arb_read_tree CLI

Example ACI (2nd expression) to generate IDs:

readdb("acc");".";readdb("start");".";readdb("stop")|merge

Related:

• allow to specify an explicit ACI in -exporter
  • use as alternative to NDS-label
  • these ACIs are identical to 2nd expression for import above
    ⇒ use same config manager?

• [16866] provides a workaround
  • synchronize IDs in original database & save
  • run script to generate special IDs (e.g. from field "full_name")
  • import
  • again synchronize IDs
  • export to file
  • quit database without saving
  • reload prev. saved database and import from file
