/**
 * A PHP version of TinyMCE's configuration, to allow various parameters to be configured on a site or section basis
 *
 * There can be multiple HTMLEditorConfig's, which should always be created / accessed using HTMLEditorConfig::get.
 * You can then set the currently active config using set_active.
 * The order of precendence for which config is used is (lowest to highest):
 *
 * - default_config config setting
 * - Active config assigned
 * - Config name assigned to HTMLEditorField
 * - Config instance assigned to HTMLEditorField
 *
 * Typically global config changes should set the active config.
 *
 * The default config class can be changed via dependency injection to replace HTMLEditorConfig.
