/*
* @file
* There is a lot of code that goes into creating the "label" of a node
* This includes editable cards with all node details, and some controls
* onCreateLabelHandler is the main function of this file, and the file
* also contains a bunch of helper functions
*
* html and littleHTML are potentially confusing variables
* html is the contents of the card shown when you click on a node's label.
* littleHTML creates little controls for removing/hiding nodes from the canvas
*
* This function features PHP-style variable substitution because the strings
* are so damn long. Values are identified by $_id_$, and then a regular
* expression is substituted in later (for html, in a separate function).
