/* HOW TO USE:
 *
 *  To set the "minutes-per-dollars" ratio:
 *
 *   1. right-click on the Greasemonkey monkey face in the status bar
 *   2. select the "Select User Script Commands" menu
 *   3. select the "Set Minutes Per Dollars" menu item
 *   4. enter in the numbers of minutes it takes you to earn $1
 *       - if it takes you more than an hour, multiply by 60 to get minutes
 *       - fractional minutes ARE allowed (15.5, for example)
 *
 * Now, go to the "Expenses Analysis" chart for your Yodlee Moneycenter account.
 * The table column titled "$ Amount" will now include the amount of time it
 * "cost" you to earn that money.
 *
 * Any time you want to update your minutes-per-dollars ratio, just select the
 * User Script Command from the Greasemonkey menu. The page will reload to
 * display the new calculations.
 *
 * CHANGELOG:
 *  v1.0 - initial release (inspired by the book "Your Money or Your Life")
 *
