int64 class stores 64-bit integers in vectors of doubles and the
base as an attribute base of the vector for printing and conversion to
character. The motivation behind this class is to give R the ability to load
64-bit integers directly, for example, to represent the commonly used 64-bit
identifiers in relational and other databases.
