/**
* This example programatically generates a series of UIViews each

* To do this we dynamically build a dictionary as we generate
* the views and simultaneously build an array of height
* constraints. Once the loop has completed we combine all of the
* constraints into a single string and apply the last constraint
* to the scrollview.
