/**
* Zikula_View function to create help link.
*
* This function creates a help link.

* - link_contents the text for the link (between the <a> and </a> tags); optional, if not specified, then the title is used.
* - icon_type an optional icon type to include in the link, separated from the link_contents (or title) by a non-breaking space; equivalent to the type parameter from the {icon} template function
* - icon_size the size of the icon (e.g., extrasmall); optional if link_icon_type is specified, defaults to 'extrasmall', otherwise ignored;
* equivalent to the size parameter of the {icon} template function
* - icon_width the width of the icon in pixels; optional if link_icon_type is specified, if not specified, then obtained from size, otherwise ignored;
* equivalent to the width parameter of the {icon} template function
* - icon_height the height of the icon in pixels; optional if link_icon_type is specified, if not specified, then obtained from size, otherwise ignored;
* equivalent to the height parameter of the {icon} template function
* - icon_alt the alternate text for the icon, used for the alt param of the {icon} template function; optional if link_icon_type is specified,
* defaults to an empty string, otherwise ignored
* - icon_title the title text for the icon, used for the title param of the {icon} template function; optional if link_icon_type is specified,
* defaults to an empty string, otherwise ignored
* - icon_optional if true and the icon image is not found then an error will not be returned, used for the optinal param of the {icon} template
* function; optional if link_icon_type is specified, defaults to false, otherwise ignored
* - icon_default the full path to an image file to use if the icon is not found, used for the default param of the {icon} template
* function; optional if link_icon_type is specified, defaults to an empty string, otherwise ignored
* - icon_right if true, then the icon is placed on the right side of the link text (the text from either link_contents or title); optional,
* defaults to false (placing the icon on the left side of the text)
* - icon_* all remaining parameters with a "icon_" prefix are passed to the {icon} function and subsequently to the <img> tag, except for
* 'icon_assign' which is completely ignored; optional if link_icon_type is specified, otherwise ignored
* - class: class for use in the <a> tag.
* - assign: if set, the results (array('url', 'link') are assigned to the corresponding variable instead of printed out.
*
* Example: A pop-up help window with a width of 400 and a height of 300, containing the contents of help.txt, and a title of 'Help'
* {helplink popup='1' width='400' height='300' filename='help.txt' title='Help'}
*
* Example: The same as above, except displayed as a button with an icon image placed on the left side of the text 'Help' separated by a non-breaking space.
* The image does not have either alternate text nor a title.
* <div class="z-buttons">
* {helplink popup='1' width='400' height='300' filename='help.txt' title='Help' icon_type='help' icon_size='extrasmall'}
* </div>
*
* Example: The same as above, except the icon's <img> tag will contain a class attrbute with the value "my_class"
* <div class="z-buttons">
* {helplink popup='1' width='400' height='300' filename='help.txt' title='Help' icon_type='help' icon_size='extrasmall' icon_class='my_class'}
* </div>
*
* @param array $params All attributes passed to this function from the template.
* @param Zikula_View $view Reference to the Zikula_View object.
