// Description:
// Summary:
// A class for creating a CContactDatabase object with random data.
// The contact items take the form of the following example:
// [KUidContactFieldFamilyName]	Fasiokljno	<5-10 chars>
// [KUidContactFieldGivenName]		Liasidwq	<5-10 chars>
// [KUidContactFieldCompanyName]	Xwjweiohj	<5-10 chars>	
// [KUidContactFieldPhoneNumber]	9874234891	<10 digits>
// Usage example:
//

// #include "dbcreator.h"
// void MyFunctionL()
// // create a database populated with 500 randomly created contact items
// const TInt KNumContacts(500);
// _LIT(KDbName, "C:mydb.cbd");
// CContactDatabase* db = DbCreator::CreateDbL(KDbName, KNumContacts);
// CleanupStack::PushL(db);
// // do something interesting...
// CleanupStack::PopAndDestroy(db);
// CContactDatabase::DeleteDatabaseL(KDbName);
