Install Dependencies

The XLS procedures have dependencies on libraries that are not included in the APOC Library.

These dependencies are included in apoc-xls-dependencies-4.1.0.10.jar, which can be downloaded from the releases page. Once that file is downloaded, it should be placed in the plugins directory and the Neo4j Server restarted.
