// Process of creating and starting server is copied from

// Richard Harrison's "Symbian OS C++ for Mobile Phones" book.

// Chapter 19 The GSDP Server, 19.3.6 Startup and Shutdown

// 

// Some differences exists: as Calendar Server is meant to be 

// running all the time, shutdown procedure is not implemented. 

// 

// Calendar server can be started two ways, whichever come firsts: 

// 1) Client connects it through client interface, in which case 

// LaunchFromClient is called.

// 2) Starter starts EXE-file, in which case process starts from E32Main 

// function (or E32Dll function in WINS)
