+ * A dialog that displays selectable symbols and allows users to drag or paste
+ * those symbols from the dialog into the document.
+ *
+ * Symbol documents are loaded from the preferences paths and displayed in a
+ * drop-down list to the user. The user then selects which of the symbols
+ * documents they want to get symbols from. The first document in the list is
+ * always the current document.
+ *
+ * This then updates an icon-view with all the symbols available. Selecting one
+ * puts it onto the clipboard. Dragging it or pasting it onto the canvas copies
+ * the symbol from the symbol document, into the current document and places a
+ * new <use element at the correct location on the canvas.
+ *
+ * Selected groups on the canvas can be added to the current document's symbols
+ * table, and symbols can be removed from the current document. This allows
+ * new symbols documents to be constructed and if saved in the prefs folder will
+ * make those symbols available for all future documents.
