/* DowMapper
 *
 * handles mapping betwen a dow (day of week, 0=sunday, 1=monday, etc) to/from an ordering position (0 to 6)
 * the week starts with the day at position 0.
 *
 * getDowStart()
 * setDowStart(dow,delta)
 * posWeekFromDow(dow)
 * dowFromPosWeek(pos)
 *
 * Plus strategy for dealing with week numbers:
 * each HISTORY stores its week number, so its easier to query without worrying about producing the right week query. Without it its hard to deal correctly
 * with boundary weeks, for example week 53 of a given year might fall into the next year thus a query by year would crop the results.
 * Once the week number is stored, we need a way to  know what standard was used (week's start day) for the row. We dont keep that standard in browser storage because it wouldnt
 * be possible to atomically change a row and setting. Thus the setting is saved in a table GLOBALS which has a single row and a column 'dowStart'
 * Additionally, we keep in storage.sync the last dowStart the user configured, and during openDb it checks if the db needs converting.
 * By convension, only openDb from the content script will cause conversion. the other callers just use the db setting. In practice, unless there is a rare case of failure,
 * the sync setting and the db setting will be in sync. The sync setting has precedence and will continue attempting to make them in sync at the next openDb call (window refresh or new tab)
