A template based class for storing ranges (lower to upper values).
QgsRange classes represent a range of values of some element type. For instance, ranges of int might be used to represent integer 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.
