Given a "container" size and a list of numbers,
return an array of array references ("containers")
which contain the supplied number list in groups of
for which the sum does notexceed the specified container
size. Further, the function should return only the
minimum number of containers required to solve the problem.
Any numbers which absolutely cannot be accomodated given
the input data and container size should be
returned "unbagged", that is, as scalar data trailing the
returned array references.
Other notes: Negative, zero, and fractional values are valid
input data for both the input list, and the container
size. As such, numbers larger than the container size cannot
be immediately discarded without first considering other input data.
@b = ( [14,1], [ 7, 6, 2], [4, 6], 22);
@o = qw [ 14 6 1 22 4 2 7 6 ];
@b = f(15,@o); # "Container size" = 15
