//This is an array, one number per year, starting at 2002.
//For example, the second line represents deaths in 2003, the third in 2004, and so on.
//The last line currently (as of 11march2011) represents those in 2011.
//To add a number to this array:
// 1.  Add a comma after the last number (but before any // on the line)
// 2.  Press 'ENTER' ('RETURN') to add a new line.
// 3.  Type the next number to add to the list.
// 4.  If desired, follow it with a space, //, and the number of the year.
// TAKE DILIGENT CARE to put // (two backward slashes) before ANYTHING EXCEPT the number of deaths and a comma (if not the last line).
