/**
* ToDo Plugin: Creates a checkbox based todo list
*
* Syntax: <todo [@username] [#]>Name of Action</todo> -
* Creates a Checkbox with the "Name of Action" as
* the text associated with it. The hash (#, optional)
* will cause the checkbox to be checked by default.
* The @ sign followed by a username can be used to assign this todo to a user.
* examples:
* A todo without user assignment
* <todo>Something todo</todo>
* A completed todo without user assignment
* <todo #>Completed todo</todo>
* A todo assigned to user User
* <todo @leo>Something todo for Leo</todo>
* A completed todo assigned to user User
* <todo @leo #>Todo completed for Leo</todo>
*
* In combination with dokuwiki searchpattern plugin version (at least v20130408),
* it is a lightweight solution for a task management system based on dokuwiki.
* use this searchpattern expression for open todos:
* ~~SEARCHPATTERN#'/<todo[^#>]*>.*?<\/todo[\W]*?>/'?? _ToDo ??~~
* use this searchpattern expression for completed todos:
* ~~SEARCHPATTERN#'/<todo[^#>]*#[^>]*>.*?<\/todo[\W]*?>/'?? _ToDo ??~~
* do not forget the no-cache option
* ~~NOCACHE~~
