Fixed a next bug: in portrait orientation the vertical size of the detail picture in the edit detail type screen depends on a picture size while it should not (made a top constraint  of a picker view to the parent view of a constant size and lowered it's priority on one point in order to avoid crash on rotating of the UI
Fixed a next bug: If the initial orientation of a change detail screen is landscape then it tries to use a portrait constraints instead of landscape ones
Implemented a test version of the instruction preview view controller which currently contains just a collection view as I'm going to start implementing a PDF export from the details list visual representation where the collection view is a good option; Added a test picture for the pin plate 1x1 to make it possible for a user to set the relative details scale
Embedded a picture image view into another view - container for it and one more view (will add later)
Linked to QuartzCore framework; Added the very first implementation of the ImageVisualFrameCalculator only for UIViewContentModeScaleAspectFit
Added an image view in order to show the pin plate image afterwords
Removed unneeded views from EditDetail and EditAssembly view controllers, to simplify code and storyboard
