A template based class for storing temporal ranges (beginning to end values).
QgsTemporalRange classes represent a range of values of some temporal type. For instance, ranges of QDateTime might be used to represent datetime ranges.
Ranges can indicate whether the upper and lower values are inclusive or exclusive. The inclusivity or exclusivity of bounds is considered when determining things like whether ranges overlap or during calculation of range intersections.

Returns true if the range is empty, ie the beginning equals (or exceeds) the end and either of the bounds are exclusive.
A range with both invalid beginning and end is considered infinite and not empty.
