+// FormattedTextBox: Displays an editable plain text node that maps to a specified Key of a Document
+//
+//  HTML Markup:  <FormattedTextBox Doc={Document's ID} FieldKey={Key's name + "Key"}
+// 
+//  In Code, the node's HTML is specified in the document's parameterized structure as:
+//        document.SetField(KeyStore.Layout,  "<FormattedTextBox doc={doc} fieldKey={<KEYNAME>Key} />");
+//  and the node's binding to the specified document KEYNAME as:
+//        document.SetField(KeyStore.LayoutKeys, new ListField([KeyStore.<KEYNAME>]));
+//  The Jsx parser at run time will bind:
+//        'fieldKey' property to the Key stored in LayoutKeys
+//    and 'doc' property to the document that is being rendered
+//
+//  When rendered() by React, this extracts the TextController from the Document stored at the 
+//  specified Key and assigns it to an HTML input node.  When changes are made tot his node, 
+//  this will edit the document and assign the new value to that field.
