// JmolApi.js -- Jmol user functions  Bob Hanson hansonr@stolaf.edu

// BH 5/29/2014 8:14:06 AM added default command for command input box
// BH 3/10/2014 10:35:25 AM adds Jmol.saveImage(applet)
// BH 1/22/2014 7:31:59 AM Jmol._Image removed -- just never found useful to have
//    a server-side process with only a client-side image. Response time is too slow.
// BH 12/13/2013 8:39:00 AM Jmol.evaulate is DEPRECATED -- use Jmol.evaluateVar
// BH 11/25/2013 6:55:53 AM adds URL flags _USE=, _JAR=, _J2S=
// BH 9/3/2013 5:48:03 PM simplification of Jmol.getAppletHTML()
// BH 5/16/2013 9:01:41 AM checkbox group fix
// BH 1/15/2013 10:55:06 AM updated to default to HTML5 not JAVA

// This file is part of JSmol.min.js. 
// If you do not use that, then along with this file you need several other files. See JSmolCore.js for details.

// default settings are below. Generally you would do something like this:

// jmol = "jmol"
// Info = {.....your settings if not default....}
// Jmol.jmolButton(jmol,....)
// jmol = Jmol.getApplet(jmol, Info)
// Jmol.script(jmol,"....")
// Jmol.jmolLink(jmol,....)
// etc. 
// first parameter is always the applet id, either the string "jmol" or the object defined by Jmol.getApplet()
// no need for waiting to start giving script commands. You can also define a callback function as part of Info.

// see JmolCore.js for details

// BH 8/12/2012 5:15:11 PM added Jmol.getAppletHtml()
