PDF_Gen37_single_column_smart_data

Browse Source 
Previously smart data was completely located
on page 2 in two columns using a variable width font.
This had two issues. The font size had to be very small
to fit on the page which made it difficult to read
and variable width fonts were used because the smart
attribute table took up too much width when all the data
was displayed in two newspaper type columns. This made the
smart attribute table look messy.

This patch now displays the smart data over page two and three
in mono spaced font and with a larger font size so it's easier
to read and the columns with the smart attribute table are now
aligned correctly.

In terms of the code, I placed the header and footer creation
code in it's own function as this is called multiple times
and will make it easier to add additional information pages
in the future.
