## Detailed Description

### template<class KEY, class VALUE, class KEYCOMPARE = std::less<const KEY>, class ALLOCATOR = std::allocator<std::pair<KEY,VALUE> >>
class GaudiUtils::VectorMap< KEY, VALUE, KEYCOMPARE, ALLOCATOR >

A bit modified version of 'LokiAssocVector' associative vector from Loki library by Andrei Alexandrescu.

The number of "non-const" operations is reduced, e.g. all non-const iterators are not exported, therefore it is almost impossible e.g. externally re-sort the underlying sorted container.

--------------------------- The nominal CPU performance: --------------------------- Container insertion: O(N) Container look-up: O(log(N)) (a'la std::map, but a bit faster)

It could be used as a "light" and good alternative for std::map associative container, in the case of relatively rare insertion and frequent look-up.
