/**
 * =popup is a universal function to generate a popup
 *
 * @author      Eric David Benari
 * @version     Release: version 1.1

Documentation for the popup function:

Usage example:
popup('url.php', 'mypopup', {'height':100, 'width':300});

Alternative syntax when multiple popups will use the same properties:
popup.height = 100;
popup.width = 300;
popup('url1.php', 'mypopup1');
popup('url2.php', 'mypopup2', {'left': 100, 'top': 150});

//the default properties can be overridden by inline definitions:
popup.focus = 1;
popup('url3.php', 'mypopup3'); //this will pop in the foreground and take focus
popup('url4.php', 'mypopup4', {'blur': true}); //this will pop in the background

The following Boolean properties are valid:
blur - sets the popup to a behind the current window
center - centers the popup on the screen
centerx - centers the popup horizontally on the screen
centery - centers the popup vertically on the screen
focus - sets the popup to take focus
replace - the fourth argument to window.open, if true, the new location will replace the current page in the browser's navigation history.
returnobject - if true, the window.open object is returned allowing you to further control the window, allowing you to do things like:
var pop = popup('page.htm', 'mypopup', {'returnobject': true});
setTimeout("closepop(pop)", 2000);

The default value is false which makes popup() return a boolean false and thus allowing you to do:
<a href="page.htm" onclick='return popup(this.href)'">

The following properties are also valid, see the API for the JavaScript window.open function for documentation:
height, width,
outerheight, outerwidth,
innerheight, innderwidth,
left, top,
screenx, screeny,
alwayslowered, alwaysraised,
channelmode, copyhistory, dependent, directories, fullscreen, hotkeys,
location, menubar, resizable, scrollbars, status, toolbar, z-lock
