Detailed Description

template<typename T>
class lar::util::MinMaxCollector< T >

Keeps track of the minimum and maximum value we observed.

Template Parameters

T	type of datum

Implementation note: a similar class with an arbitrary comparison rule would require a careful choice of initial values for minimum and maximum, or a entry count that should be checked at each insertion. We save that slight overhead here.
