# The document grid on Prawn is just a table-like structure with a defined
# number of rows and columns. There are some helpers to create boxes of content
# based on the grid coordinates.
#
# <code>define_grid</code> accepts the following options which are pretty much
# self-explanatory: <code>:rows</code>, <code>:columns</code>,
# <code>:gutter</code>, <code>:row_gutter</code>, <code>:column_gutter</code>
