 * \class PixInsightSettings
 * \brief Retrieves global settings from the PixInsight core application
 *
 * PixInsight global settings, also known as <em>global variables</em>, are
 * identifier/value pairs available from the core application to all installed
 * modules. Settings can be of six types: flags (or Boolean), integer (signed
 * and unsigned), real (floating point), color, font, and string. See the
 * pcl::GlobalVariableType namespace for more details.
 *
 * Below is a complete list of all global settings available in current
 * versions of the PixInsight platform (updated as of core version 1.8.8-13).
