 /**
  * Date range representation.

  * Piwik allows users to view aggregated statistics for single days and for date
  * ranges consisting of several days. When requesting data, a **date** string and
  * a **period** string must be used to specify the date range that the data regards.
  * This is the class Piwik uses to represent and manipulate those date ranges.
- * 
+ *
  * There are five types of periods in Piwik: day, week, month, year and range,
  * where **range** is any date range. The reason the other periods exist instead
  * of just **range** is that Piwik will pre-archive reports for days, weeks, months
