Added angle correction on guide, fixed voiceover guide by taking the center of the found sheet and the center of the view to guide, changed boundingRect to get a RotatedRect from the sheet, which is almost the same of the recognised sheet. Added ways to print this new data into the image. Added release() calls inside of findAndDrawSheetByContours:.
Added a lot of releases into the code to fix memory issues, added a CGImageRelease on the end of findAndDrawSheetByContours:, added free(_pixels) in Tesseract.mm (and made  a pull request to the repository). Changed how the CMSampleBuffer is converted to UIImage by using an method found in Apple Docs and not by passing it to a CIImage. Added a NSTimer to limit the times that the sheet is found to maintaing the memory at a low use, the sheet is now found 10 times a second, not 30 like before, following AVCapture’s FPS. The memory is not dependent on didReceivedMemoryWarning anymore. Removed Speech-related option from settings, added a initialiser to segment control to match dataClass.tesseractLanguage. Added french support (only in tesseract, internationalization still to come). Added edit button on history tab. Added fra.tessdata into the project. Removed QuartzCore.framework from project. Changed
