// This file defines granular debugging flags that may be switched on and off
// at run time.  Typical usage is 'if(ISDEBUG("myFunction"))' to check if the
// 'myFunction' flag is enabled, and SETDEBUG("myFunction", true) to enable
// this flag, or SETDEBUG("myFunction", false) to disable it.
//
// Debug flags are created automatically as they are accessed, so they can be
// used immediately without explicitly creating them.  Each flag defaults to
// 'false', i.e. disabled.
//
// For these macro to have any effect, granular debugging must be enabled by
// defining GTSAM_ENABLE_DEBUG.  If NDEBUG is not defined, then
// GTSAM_ENABLE_DEBUG will be automatically defined and thus granular
// debugging enabled.
