			- movingAverageSpeed -- Speed over averaged over the last several measurements, bytes per second
			- timeRemaining -- Estimated remaining upload time in seconds
			- timeElapsed -- Number of seconds passed for this upload
			- percentUploaded -- Percentage of the file uploaded (0 to 100)
			- sizeUploaded -- Formatted size uploaded so far, bytes
		
		*Adds setting 'moving_average_history_size' for defining the window size used to calculate the moving average speed.
		
		*Adds several Formatting functions for formatting that values provided on the file object.
			- SWFUpload.speed.formatBPS(bps) -- outputs string formatted in the best units (Gbps, Mbps, Kbps, bps)
			- SWFUpload.speed.formatTime(seconds) -- outputs string formatted in the best units (x Hr y M z S)

			- SWFUpload.speed.formatUnits(baseNumber, divisionArray, unitLabelArray, fractionalBoolean)
