The product summary Overview needs to display rows for a product's
Attributes, whose data are fetched from the newly integrated
ProductAttribute API endpoint. This required a subclass of UIView and a
new class of TableView Cells to hold them. When the user taps an
Attribute row, a pop-up info card will be displayed showing a longer
description. Swiping left will show more related information on the
pop-up info card.

This snapshot is not workable, I just want to preserve an idea which
probably won't work, which is passing a closure to
AttributeTableViewCell to launch the floatingPanel. However, I made
FormTableViewController the owner of the floating panel and that is not
allowed. So now I am switching to a new strategy to make a delegate for
AttributeTableViewCell and designate the
ProductDetailTableViewController as the delegate and as the floating
panel host as I originally intended.

Created delegate protocol for AttributeTableViewCell to call back to
ProductDetailViewController so it can launch the FloatingPanelVC
Extend ProductDetailVC so it can handle FloatingPanels similar to
ScannerViewController. Create ProductAttributeViewController.swift and
.storyboard to be the FloatingPanels VC and view to hold AttributeView

Add the frame of the image to the exclusion path of the text view.
Create func getIconAspectConstraint() to get the dynamic aspect ratio of
the image in code so we can dynamically adjust the imageView height and
width. Place image related code in completion handle of KingFisher
setImage(with: resource) to ensure the adjustments are attempted after
the image is retrieved.
