+/**
+ * DataTables has a built in type called 'html' which will strip HTML tags 
+ * from a search string, but it doesn't cope with nested HTML inside another 
+ * element's attributes (for example DOM0 events with have HTML in them). This
+ * plug-in function overrules the built-in method and provides complete HTML
+ * tag removal. Note that this function is not included in DataTables by
+ * default because it is slightly slower than the built-in method, which is
+ * good enough for by far the majority of use cases.
