Objects deletion tool and various fixes

[XavDmz]

Changelog

[Added]

• delete_data executable : cascade delete objets from any table, following lists of identifiers.
• SQL structures initialisation scripts:
  • one file dedicated to declaration raw data import (target for import_declaration)
  • one file for the main structures used by the pairing tool (pair_from_sources)
  • not tested : delete_data may probably work only on the main structures (because of the cascade deletion)

[Changed]

• functions from delete_data module are used by pair_from_sources.
• declaration input data specifications changes were implemented in import_declarations
• import_declaration is more permissive and imports any delcaration dossier from source. Use of two different tables, schema or database (your choice) is recommended to distinguish between the following:
  • raw imported declaration data: simple SQL extraction of the remote source data
  • filtered partial declaration data: used for pairing and further visualisation.

[Fixed]

• detection objects' geometries construction method created invalid multipolygons. (contained polygons shared edges) Now the construction process ensures the geometry's validity.
• Miscommunications on detection input data specs caused SQL insertion errors. The table definition has been modified to ensure a unique integer identifier.
