Eliminated unnecessary ServiceLocator/ConfigReader in VuFind\Cart; dependencies and configuration are now injected through constructor.

Added CollectionSideFacets recommendation module and set it up to be active by default in collection view.

Made record router smart enough to figure out collection links even if not given a full record driver object.

Made record router a service rather than a static class to enable dependency injection and easier overriding.

Revised Solr Tree Data Source to use record drivers instead of direct array access to Solr response.

Created collection controller; for starters, just an extension of AbstractRecord with a few minor changes and some cloned Solr Record templates.

made Authority module more robust by standardizing routing.

- Decoupled record drivers from tab rendering
- Every record tab now has a corresponding class and template
- Record driver => tab mapping is handled through module.config.php
- Added some missing comments to existing code

Switched to dependency injection for cleaner WorldCatIdentities/WorldCatTerms recommendation modules.

Improved initialization of translator; renamed service to VuFind\Translator; added some missing comments.

Renamed 'logger' service to 'VuFind\Logger' to avoid conflicts; updated all logger-dependent classes to use Zend\Log\LoggerAwareInterface; set up standard initializer for main service manager and other factories.

Prefixed plugin manager service names with "VuFind\" as first step toward best-practice naming for global services.

Use explicit dependency injection for ILS authentication module instead of relying on service locator.

  - Eliminated dependency on ServiceLocatorAwareInterface by creating more targeted initWithDriverManager method
  - Added setDriver method to enable more flexible usage/testing
  - Implemented fluent interface on setConfig/setDriver to simplify factory routine
  - Made some methods more tolerant of missing configuration settings
