Fixed a bug that causes the data acquisition to crash: The fits writer hangs so the bulk data transfer timeout and crashes. The cause was due to an antennaBoss deadlock: the routine to compute the observed coordinates never escapes a for loop when the observed coordinate vector was full. Added a TimeTaggedCircularArray test routine. Fixed the TotalPower container in order to avoid the first acquired sample to be scrambled when backend latency time is not completely respected. Added debugging (in order to detect unreleased mutex) method for SecureArea class.
