/**
* Class containing "advanced" configuration options.
*
* Options set here are for developer or advanced users only. If a general user
* needs to set one of these for normal KiCad use, either:
* * They are working around some bug that should be fixed, or
* * The parameter they are setting is of general interest and should be in the
* main application config, with UI provided.
*
* Options in this class are, in general, preferable to #defines, as they
* allow more flexible configuration by developers, and don't hide code from
* the compiler on other configurations, which can result in broken builds.
*
* Never use advanced configs in an untestable way. If a function depends on
* advanced config such that you cannot test it without changing the config,
* "lift" the config to a higher level and make pass it as parameter of the code
* under test. The tests can pass their own values as needed.
*
* This also applies to code that does not depend on "common" - it cannot
* use this class, so you must pass configuration in as proper parameters.
*
* Sometimes you can just use values directly, and sometimes helper functions
* might be provided to allow extra logic (for example when a advanced config
* applies only on certain platforms).
*
* For more information on what config keys set these parameters in the
* config files, and why you might want to set them, see #AC_KEYS
*
