            <p>Allows specifying default properties to apply to an item when it is initialized,
if those values are not provided to the initializer.
Only non-nil values are used – if you do not want to provide a default value,
simply leave the property nil.</p>

<p>The order of precedence used when assigning values is:
1) The value passed to the initializer.
2) The value from <code>defaultItemProperties</code>
