/**
 Depending on the width of the application window, all of the content views in
 the passcode view need to be resized in order to fit in the available space.

 This means that not only does the spacing and sizing of views need to be changed, but
 image assets need to be regenerated and font sizes need to change as well.

 This class assumes there will be three major screen sizes, and provides layout
 sizes, spacing, and styles in order to resize the passcode view for each one.

 The three screen styles it supports are:

 * Small Screens - iPhone 5/ or iPad 9.7" in 1/4 split screen mode
 * Medium Screens - iPhone 6/ or iPad 12.9" in 1/4 split screen mode
 * Large Screens - iPhone 6 Plus and all iPads when not in split screen mode.
