Rework ATWriter/Exporter - Make the write function static as both data and gauge information is necessary for writing. - Use the rivers WST unit for the gauge datum - Handle the case that we are at a gauge - Differentiate between calculated values - Always work with w in CM and thus avoid double number format problems
