/**
Class offers static methods for parsing and validating phone numbers. 
Phone Parser API provides methods which are used to parse and validate
phone numbers. The API consists of the TulPhoneNumberUtils class.

Examples of valid phone numbers:
1.	+358501234567
2.	+358 (50) 123 4567

Even though both of the above examples are valid phone numbers, only 1) is 
accepted as a phone number by many systems. To convert 2) to 1), use the 
parsing method of the API.

Usage:
  
@code
 #include <tulphonenumberutils.h> 

 // Example shows how to use the parsing method of the API.

 // A number to be parsed. 
 TBuf<50> number1 = _L("+358 (40) 123 132");

 // Type of the phone number to be parsed is a regular phone number.
 TBool validNumber1 = 
 TulPhoneNumberUtils::NormalizePhoneNumber( number1,
                                      TulPhoneNumberUtils::EPlainPhoneNumber );

 // The phone number number1 is a valid regular phone number.
 // After parsing validNumber1 is ETrue and 
 // number1 is "+35840123132".
 // Do something like SendSMS( number1 ) etc.

 // A number to be parsed. 
 TBuf<50> number2 = _L("+358 (40) 123p132"); // note 'p'

 // Type of the phone number to be parsed is a regular phone number.
 TBool validNumber2 = 
 TulPhoneNumberUtils::NormalizePhoneNumber( number2,
                                      TulPhoneNumberUtils::EPlainPhoneNumber );

 // The phone number number2 is not a valid regular phone number.
 // After parsing validNumber2 is EFalse and 
 // number2 is "+358 (40) 123p132" (unchanged).
