Document should support :margins

[practicingruby]

Allow :margins => [a,b,c,d] or even :margins => k

Added a :margin option:

I suppose I could add in support for [a,b,c,d]. Is there a conventional order? In CSS it's top, right, bottom, left. Same here?

[practicingruby]

yeah, that would be fine.

Okay, pushed to my master. Both Document#initialize and Document#start_new_page now support :margin, and it can take anything from a single value to four values:

# The :margin can also be an array much like CSS shorthand:
#
#   # Top and bottom are 20, left and right are 100.
#   :margin => [20, 100]
#   # Top is 50, left and right are 100, bottom is 20.
#   :margin => [50, 100, 20]
#   # Top is 10, right is 20, bottom is 30, left is 40.
#   :margin => [10, 20, 30, 40]

So fetch me and e.g.

git cherry-pick 2bab3fc76ecdadfae1e858d422530aa10f955f4c^^
git cherry-pick 2bab3fc76ecdadfae1e858d422530aa10f955f4c^
git cherry-pick 2bab3fc76ecdadfae1e858d422530aa10f955f4c

to get the commits. Or just merge. I rebased sandal/master, so my commits are on top of it.
