// This class is a "logical time span" and is useful for implementing program
// logic for such things as "add one month to the date" which, in general,
// doesn't mean to add 60*60*24*31 seconds to it, but to take the same date
// the next month (to understand that this is indeed different consider adding
// one month to Feb, 15 - we want to get Mar, 15, of course).
//
// When adding a month to the date, all lesser components (days, hours, ...)
// won't be changed unless the resulting date would be invalid: for example,
// Jan 31 + 1 month will be Feb 28, not (non existing) Feb 31.
//
// Because of this feature, adding and subtracting back again the same
// wxDateSpan will *not*, in general give back the original date: Feb 28 - 1
// month will be Jan 28, not Jan 31!
//
// wxDateSpan can be either positive or negative. They may be
// multiplied by scalars which multiply all deltas by the scalar: i.e. 2*(1
// month and 1 day) is 2 months and 2 days. They can be added together and
// with wxDateTime or wxTimeSpan, but the type of result is different for each
// case.
//
// Beware about weeks: if you specify both weeks and days, the total number of
// days added will be 7*weeks + days! See also GetTotalDays() function.
//
// Equality operators are defined for wxDateSpans. Two datespans are equal if
// they both give the same target date when added to *every* source date.
// Thus wxDateSpan::Months(1) is not equal to wxDateSpan::Days(30), because
// they not give the same date when added to 1 Feb. But wxDateSpan::Days(14) is
// equal to wxDateSpan::Weeks(2)
//
// Finally, notice that for adding hours, minutes &c you don't need this
// class: wxTimeSpan will do the job because there are no subtleties
// associated with those.
