Renamed 'MainPage.xaml', the associated .xaml.cs file, and the code objects therein to WordClouderizerView.xaml. Additionally fixed an error wherein the UpdateCloudWord_Click() method in the view was trying to cast a Button to a RichTextBox instead of referring to WordsTextBox. Additionally added a conditional after the Text string is split and counted to abort generating WordModels if there are no valid word strings in Text.
