//
// 1. BOOL MultiCookie($CID,$Debug,$Expire,$Domain,$Secure)
// class Initialization function. $CID is cookie name to use and $Debug is
// parameter for debug check. Remainder parameter are same with parameter
// of setcookie function.
// Ex ) $MultiCookie = new MultiCookie("Login");
//
// 2. BOOL Create()
// Function that create cookie. Parameter of "key=>value" form.
// Is stored with "1=>a:2=>b:3=>c:4=>d" in file.
// Ex ) MultiCookie->Create("id=>ifsnow","passwd=>12345","level=>99");
//
// 3. Destroy($Set)
// Erase cookie and initialize interior variables. If $Set is TRUE,
// erase cookie.
// Ex ) $MultiCookie->Destroy();
//
// 4. Parsing()
// Because reading cookie, analyze and store in array.
// Ex ) $MultiCookie->Parsing();
//
// 5. String Read($Key)
// Return the value of an array.
// Ex ) $id = $MultiCookie->Read("id");
//
// 6. BOOL AddNew()
// Add new value to existent cookie.
// Ex ) $MultiCookie->AddNew("email=>lsm@ebeecomm.com","icq=>71930801");
//
// 7. BOOL Modify()
// Modify value of existing cookie.
// Ex ) $MultiCookie->Modify("passwd=>34567","level=>100");
//
// 8. BOOL Delete()
// Erase value of existing cookie.
// Ex ) $MultiCookie->Delete("email","icq");
//
// 9. BOOL IsExist($Key)
// Return TRUE if a $Key exists in an array;
// Ex ) $MultiCookie->IsExist("id")==TRUE ? "O":"X";
//
// 10. Info()
// Display information of cookie.
// Ex ) $MultiCookie->Info();
