/**
* 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.
