Classes: Create view cell

[mihaivarga]

ViewCell should be a controller that renders as a variable with toString processing to html.

View cells can be used for common templates with controller rendering between components.

example:

user.cell.php
user.cell.tpl

class UserCell extends ViewCell {
function display(){
$this->assign('var',$value)
}
}

Loading View Cell in controllers:

$userCell=$this->cell('user');
$this->assign('usercell',$userCell);

Showing a cell in a view:

{$usercell}

Loading a cell directly in template:

{viewcell name="user"}
