Documentation

The documentation on the_pack_ and_align_ variables for theStructure andUnion classes needs elaboration. Currently, both say something to the effect of "An optional small integer that allows overriding the alignment of the structure..."

The documentation is clear that setting either parameter to 0 has no effect. However, it is unclear what effect setting the value to anything other than 0 has. Is it a true/false value? Does it set the number of bits to which each field should be aligned and/or padded and/or truncated? Does it override the third tuple parameter when setting fields? What happens if it's set to a negative number?
