the class AdvancedStatistics method calculateDueAsMetaInfo.

/**
 * Determine forecast statistics based on a computation or simulation of future reviews.
 * Returns all information required by stats.java to plot the 'forecast' chart based on these statistics.
 * The chart will display:
 * - The forecasted number of reviews per review type (relearn, mature, young, learn) as bars
 * - The forecasted number of cards in each state (new, young, mature) as lines
 * @param metaInfo Object which will be filled with all information required by stats.java to plot the 'forecast' chart and returned by this method.
 * @param type Type of 'forecast' chart for which to determine forecast statistics. Accepted values:
 *             Stats.TYPE_MONTH: Determine forecast statistics for next 30 days with 1-day chunks
 *             Stats.TYPE_YEAR:  Determine forecast statistics for next year with 7-day chunks
 *             Stats.TYPE_LIFE:  Determine forecast statistics for next 2 years with 30-day chunks
 * @param context Contains The collection which contains the decks to be simulated.
 *             Also used for access to the database and access to the creation time of the collection.
 *             The creation time of the collection is needed since due times of cards are relative to the creation time of the collection.
 *             So we could pass mCol here.
 * @param dids Deck id's
 * @return @see #metaInfo
