This method inserts values and qualities into the history database at the specified timestamps for one or more items. If a value exists at the specified timestamp, the new value shall not be inserted; instead errors shall indicate an error. This method is intended to insert new values at the specified timestamps; e.g., the insertion of lab data to reflect the time of data collection. The serverHnd, timeStamps, dataValues and qualities are arrays of equal size. To insert a value for a number of different items at a single time, then timeStamp array would have the same time for each item. To insert a stream of values, timestamps and qualities for a single item, set the size of the item array to the number of values to be inserted and put the same ItemID in each element.
