 ### Finalizing a array
 When the configurations for an array is finalized then the ecmcDAQFinalizeArray.cmd must be called.
 The command will read the total array size (header plus data) from the plugin and then load the database with the waveform record (with correct NELM). The command takes the array name as a parameter ("NAME").
