columnize 0.3.0

Format a list of strings into a single compact string

Return a list of strings as a compact set of columns arranged
horizontally or vertically.

For example, for a line width of 4 characters (arranged vertically):
['1', '2,', '3', '4'] => '1 3\n2 4\n'

or arranged horizontally:
['1', '2,', '3', '4'] => '1 2\n3 4\n'

Each column is only as wide as necessary. By default, columns are
separated by two spaces - one was not legible enough. Set "colsep"
to adjust the string separate columns. Set `displaywidth' to set
the line width.

Normally, consecutive items go down from the top to bottom from
the left-most column to the right-most. If +arrange_vertical+ is
set false, consecutive items will go across, left to right, top to
bottom.
