/**
* SWP_Link_Manager
*
* A class engineered to manage the links that are shared out to the various social
* networks. This class will shorten them via Bitly or add Google Analytics tracking
* parameters if the user has either of these options enabled and configured.
*
* Organization - This class has one primary function: It provides a publicly
* accessable method that applies the link-modifying filters.
*
*    This will provides the plugin with an easy to access, static method which
*    can be called from anywhere with minimal properties to quickly fetch a
*    fully processed sharable link for the buttons.
*
* @since 3.0.0 | 14 FEB 2018 | Added check for is_attachment() to swp_google_analytics
* @since 3.0.0 | 04 APR 2018 | Converted to class-based, object-oriented system.
* @since 4.0.0 | 17 JUL 2019 | Refactored into a more expandable system so that
*                              we can easily add multiple link shortening services.
