xintf - Improved coloration behavior.
	Added Time from Second checkbox to flip between time from trigger and time from the beginning of a second
intf_process - 	Reverted processing times to be referenced to the trigger time (since the data is still written this way)
intf_tools -	Changes made to the filter function, which may now break it's use on Nx1 arrays,
		but allow it to work for NxM arrays.  I should fix this
