Title: A S3 class for vectors of 64bit integers

Description: Package 'bit64' provides serializable S3 atomic 64bit
(signed) integers that can be used in vectors, matrices, arrays
and data.frames. Methods are available for coercion from and to
logicals, integers, doubles, characters as well as many
elementwise and summary functions.  With 'integer64' vectors
you can store very large integers at the expense of 64 bits,
which is by factor 7 better than 'int64' from package 'int64'.
Due to the smaller memory footprint, the atomic vector
architecture and using only S3 instead of S4 classes, most
operations are one to three orders of magnitude faster: Example
speedups are 4x for serialization, 250x for adding, 900x for
coercion and 2000x for object creation. Also 'integer64' avoids
an ongoing (potentially infinite) penalty for garbage
collection observed during existence of 'int64' objects (see
code in example section).  Last but not least, this package has
no commercial copyright attached, it is not sponsored by any
commercial company or otherwise influenced by commercial
interests. Its mix of high-level R code with low-level C-code
protects against misuse outside the GPLed R context.
