Can you please add an ability to add a Component into PullPickerView?

Hello rilyu,

First of all, many thanks for you to provide this great UI library.
I had a suggestion about this library.

teaset/components/PullPicker/PullPickerView.js

Lines 56 to 59 in d36cb7b

	{!title ? null :
	<View style={headerRowStyle}>
	<Label style={headerTextStyle} text={title} />
	</View>

Here, I want you to add something like this.
Is this possible?

       {!title ? null :
          <View style={headerRowStyle}>
            {typeof(title) === 'string' || (title && title.type && title.type.displayName === 'Text') 
            ? <Label style={headerTextStyle} text={title} /> 
            : title}
          </View>
        }
