/*
|
|
* @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).
