New QgsRange template based class for storing interval ranges

Browse Source 
QgsRange classes represent a range of values of some element
type. For instance, ranges of QDateTime might be used to
represent the ranges of timestamp 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.

Includes typedefs for QgsDoubleRange, QgsIntRange, QgsDateRange.
