class TExifReaderUtility;
Description
This class offers a friendly interface to read the metadata in exif encoded image files
Note: Unless otherwise stated in a method's documentation, TInt& arguments represent unsigned quantities and will be updated
with unsigned values, even though TInt is a signed type. In such cases, proper typecasting should be used to ensure that the
values are correctly treated as unsigned.
Note: Get method arguments will only be updated if the method is returning KErrNone.
