Implemented rotation, scaling, with critical UI elements on top of stack.
Tie positioned very close to correct spot on stamped images.  Branding also stamped in bottom left corner.
explanatory comments in implementation file
Two new ties and some other ties brightened up a bit.
Panning works with two fingers in addition to all existing gestures and swipes.  Also removed blank startup splash screen images.
New method for combining images that uses an adjusted target-size to match the previewLayer size.  Avoids some math, introduces other math.
Image construction and tie positioning is complete.  Just have the whole “wrong tie” bug to work through now. -N8
Moved tie image loading code together with display updates.  Appears to resolve most of issue #1
Changed hard-coded screen size value to use frame of viewController per issue #3.  Needs testing on iPhone 5 or 5s or 5c.
Cooky flash animation added to the capture operation so people know something happened.
Added three new ties.
Updated branding images for launch screen.
Fixes marketing stuff in issues #6 and #7.  Could be released as-is if needed.
Closed #3 but ties are *slightly* stretched in the iPhone 5 version.  However, this keeps the positioning mechanism accurate for generating the photos.
Made the Tie Rack Scheme a shared scheme for Continuous Integration.  Other changes that are too old to remember.
