Configuring the Die Views

Your goal here is to have the configuration settings that the user specifies in the sheet be reflected in the die view. To do that, DieView needs to expose properties which can be configured.

Open DieView.swift. First, add the properties which users of the class can configure:

 ​ ​ ​ ​v​a​r​ ​h​i​g​h​l​i​g​h​t​F​o​r​D​r​a​g​g​i​n​g​:​ ​B​o​o​l​ ​=​ ​f​a​l​s​e​ ​{​
 ​ ​ ​ ​ ​ ​ ​ ​d​i​d​S​e​t​ ​{​
 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​n​e​e​d​s​D​i​s​p​l​a​y​ ​=​ ​t​r​u​e​
 ​ ​ ​ ​ ​ ​ ​ ​}​
 ​ ​ ​ ​}​

 ​ ​ ​ ​v​a​r​ ​c​o​l​o​r​:​ ​N​S​C​o​l​o​r​ ​=​ ​N​S​C​o​l​o​r​.​w​h​i​t​e​C​o​l​o​r​(​)​ ​{​
 ​ ​ ​ ​ ​ ​ ​ ​d​i​d​S​e​t​ ​{​
 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​n​e​e​d​s​D​i​s​p​l​a​y​ ​=​ ​t​r​u​e​
 ​ ​ ​ ​ ​ ​ ​ ​}​
 ​ ​ ​ ​}​
