 Compiler warnings, such as deprecations and others are normally warned about, but compilation continues. In strict mode,
 these warnings instead trigger a compile error, and must be fixed immediately. However, in combination with the 
 suppressWarnings file option, individual warnings can be ignored, and these will trigger neither a compiler warning or
