	// 6 - Alert(Go to PP?) OK, Cancel. Ok: PP in same window. Cancel: TB like 3
	// 7 - Check but do nothing. (IE will auto install. NN will have link to PP)
	// 8 - Get plugin here. IE:auto download & alert. NN4: alert, trigger download, TB with refresh link. NN6: TB link to EXE.

	// 10- Call CustomEonXStatusHandler() and cancel EONInsert - Use to show alternative content.

//  --- INSERT EON OBJECT ---

//  This function will insert the embed or the object tag which displays 
//  the EON simulation. The reasons for doing this are:
//  1. In Netscape, EONX will only look in the codebase given. It doesn't look
//     where this web page is like IE does. This function dynamically writes the
//     EONX object/embed tag and calculates the directory this file is in whether
//     it be on the Internet, a CD or local harddisk. It's called the documentbase.
//     Now if we move the webpage we don't have to update the path to the simulation.
//  2. Saves time for the programmer to write down one set of values instead of two.
//  3. Forces the use of names or id that are used in all the functions of this file.
//  4. Reduces space in the webpage file. ( Write just EONInsert() instead of all below.)
