/**
* Sub-class specialization of EventHandler base class.
*
* TaskLoop allows to schedule a task function being called (optionnaly repeatedly) on the main loop,
* scheduled asynchroneously, avoiding recursive calls in the same tick.
*
* The task itself is implemented in `doTick`. It can be requested and called for single execution
* using the `tick` method.
*
* It will be assured that the task execution method (`tick`) only gets called once per main loop "tick",
* no matter how often it gets requested for execution. Execution in further ticks will be scheduled accordingly.
*
* If further execution requests have already been scheduled on the next tick, it can be checked with `hasNextTick`,
* and cancelled with `clearNextTick`.
*
* The task can be scheduled as an interval repeatedly with a period as parameter (see `setInterval`, `clearInterval`).
*
* Sub-classes need to implement the `doTick` method which will effectively have the task execution routine.
*
* Further explanations:
*
* The baseclass has a `tick` method that will schedule the doTick call. It may be called synchroneously
* only for a stack-depth of one. On re-entrant calls, sub-sequent calls are scheduled for next main loop ticks.
*
* When the task execution (`tick` method) is called in re-entrant way this is detected and
* we are limiting the task execution per call stack to exactly one, but scheduling/post-poning further
* task processing on the next main loop iteration (also known as "next tick" in the Node/JS runtime lingo).

* Sub-class specialization of EventHandler base class.
*
* TaskLoop allows to schedule a task function being called (optionnaly repeatedly) on the main loop,
* scheduled asynchroneously, avoiding recursive calls in the same tick.
*
* The task itself is implemented in `doTick`. It can be requested and called for single execution
* using the `tick` method.
*
* It will be assured that the task execution method (`tick`) only gets called once per main loop "tick",
* no matter how often it gets requested for execution. Execution in further ticks will be scheduled accordingly.
*
* If further execution requests have already been scheduled on the next tick, it can be checked with `hasNextTick`,
* and cancelled with `clearNextTick`.
*
* The task can be scheduled as an interval repeatedly with a period as parameter (see `setInterval`, `clearInterval`).
*
* Sub-classes need to implement the `doTick` method which will effectively have the task execution routine.
*
* Further explanations:
*
* The baseclass has a `tick` method that will schedule the doTick call. It may be called synchroneously
* only for a stack-depth of one. On re-entrant calls, sub-sequent calls are scheduled for next main loop ticks.
*
* When the task execution (`tick` method) is called in re-entrant way this is detected and
* we are limiting the task execution per call stack to exactly one, but scheduling/post-poning further
* task processing on the next main loop iteration (also known as "next tick" in the Node/JS runtime lingo).

Style HTML
---------------
Written by Nochum Sossonko, (nsossonko@hotmail.com)
Based on code initially developed by: Einar Lielmanis, <elfz@laacz.lv>
http://jsbeautifier.org/
Usage:
style_html(html_source);
style_html(html_source, options);
The options are:
indent_inner_html (default false) — indent <head> and <body> sections,
indent_size (default 4) — indentation size,
indent_char (default space) — character to indent with,
wrap_line_length (default 250) - maximum amount of characters per line (0 = disable)
brace_style (default "collapse") - "collapse" | "expand" | "end-expand"
put braces on the same line as control statements (default), or put braces on own line (Allman / ANSI style), or just put end braces on own line.
unformatted (defaults to inline tags) - list of tags, that shouldn't be reformatted
indent_scripts (default normal) - "keep"|"separate"|"normal"
preserve_newlines (default true) - whether existing line breaks before elements should be preserved
Only works before elements, not inside tags or for text.
max_preserve_newlines (default unlimited) - maximum number of line breaks to be preserved in one chunk
indent_handlebars (default false) - format and indent {{#foo}} and {{/foo}}
e.g.
style_html(html_source, {
'indent_inner_html': false,
'indent_size': 2,
'indent_char': ' ',
'wrap_line_length': 78,
'brace_style': 'expand',
'unformatted': ['a', 'sub', 'sup', 'b', 'i', 'u'],
'preserve_newlines': true,
'max_preserve_newlines': 5,
'indent_handlebars': false
});
