Make a new popup window...
Parameters:
  oAnchor: required object reference to the anchor (link)
  sWindow: optional string for the window name if wanting to reuse window or null to use the default.
  sProps: optional string of window properties ('width=300,height=200') or null to use the defaults defined here.
Notes:
  Notice in the example that the 'href' value maintains URL
  (not "#" or "javascript:") and the 'title' attribute indicates
  this will be a pop-up window. These things are required for
  accessibility reasons.
Example use:
  <a href="/home.jsp" onclick="return pop(this,'survey');" title="Survey opens a new window.">Take our survey!</a>
