/**
 * Historically, this plugin started out working against an IMS-neutral XML file, and then added extensive support for
 * JIRA with some small snippets of code for other issue management systems. This class is intended to start a cleaner
 * modularity for support of multiple systems.<br>
 * Initially, all it provides is a structure for mapping from per-IMS issue types to the three categories defined in
 * {@link org.apache.maven.plugin.changes.IssueAdapter}. <br/>
 * Note that the map in here is <strong>not</strong> immutable. It contains the default configuration for an IMS. Users
 * are expected to add entries to the map via configuration to reflect their customizations.
