// Launches a process by means of the debug engine.
// Normally, Visual Studio launches a program using the IDebugPortEx2::LaunchSuspended method and then attaches the debugger
// to the suspended program. However, there are circumstances in which the debug engine may need to launch a program
// (for example, if the debug engine is part of an interpreter and the program being debugged is an interpreted language),
// in which case Visual Studio uses the IDebugEngineLaunch2::LaunchSuspended method
// The IDebugEngineLaunch2::ResumeProcess method is called to start the process after the process has been successfully launched in a suspended state.
