// CHANGES to 'JSVApplet.java' - Web Application GUI
// University of the West Indies, Mona Campus
//
// 09-10-2007 commented out calls for exporting data
//            this was causing security issues with JRE 1.6.0_02 and 03
// 13-01-2008 in-line load JCAMP-DX file routine added
// 22-07-2008 reinstated calls for exporting since Ok with JRE 1.6.0_05
// 25-07-2008 added module to predict colour of solution
// 08-01-2010 need bugfix for protected static reverseplot
// 17-03-2010 fix for NMRShiftDB CML files
// 11-06-2011 fix for LINK files and reverseplot 
// 23-07-2011 jak - Added parameters for the visibility of x units, y units,
//            x scale, and y scale.  Added parameteres for the font,
//            title font, and integral plot color.  Added a method
//            to reset view from a javascript call.
// 24-09-2011 jak - Added parameter for integration ratio annotations.
// 08-10-2011 jak - Add a method to toggle integration from a javascript
//          call. Changed behaviour to remove integration after reset view.
// 19-06-2012 BH -changes to printing calls
// 23-06-2012 BH -Major change to Applet code to allow multiple file loads
// 28-06-2012 BH -Overlay/close/view spectrum dialog working SVN 961
// 02-07-2012 BH -show distances between peaks
// 04-07-2012 BH -Ctrl- PgUp/PgDn for 2D spectra 
// 06-07-2012 BH -Views menu implemented
// 08-07-2012 BH -refactoring of Graph, add new NMR dialog boxes
// 14-07-2012 BH -IR peak listing
// 17-07-2012 BH -getProperty key
// 18-07-2012 BH -MAC fix for repaint
