* change types of minHeight and maxHeight to CGFloat to maintain type
  compatibility with CGSize
* allow setting minHeight and maxHeight to custom values
* sizeToFit now readjusts frame height if necessary

Add placeholder string option
Merge pull request #22 from timothyarmes/master
Added animationDuration property
Merge branch 'animation-duration'
Added animationDuration to the README
Merge branch 'animation-duration'
Don't draw the placeholder text until the view is done animating.
(When animating from a text view containing a single newline character to an empty text view, the placeholder text would appear stretched as the view animated from two lines to one)
Merge branch 'placeholder'
Added a dealloc method to release the internalTextView
Merge branch 'dealloc'
Removed dealloc.
Merged dkharrat's modifications for re-sizing with minimum/maximum heights.
Call resetSize in ViewController's willAnimateRotationToInterfaceOrientation:duration method to have resizing work properly. This isn't the best solution…but better than nothing.
Optimized minHeight and maxHeight calculation
Optimized initialization of default attributes
Vars that should be floats now float; vars that should be doubles now double.
Updated README.md
Removed an old comment.
