# HtmlTableInlineWriter
#   This class is an extension to the HtmlTableWriter and uses an instance of it to generate an HTML
#   table through a simplified interface. The public interface consists of 2 functions:
#     - WriteData(self, data, column, row)
#   and
#     - End(self)
#   
#  It is intended that this class is used when you have too much data to store and want to dump it
#  to file as it is processed. The data is expected to be sparse (meaning that rows or columns might
#  need to be skipped) and this class deals with writting "filler" elements to get you to the
#  correct cell that you want to write. One restriction of this implementation (and HTML in general)
#  is that you must write the cells out in a particular order.
#  
#  Given the following example table:
#    [ A, b, 6 ]
#    [ 7, X, y ]
#  
#  You would need to call WriteData and give it the data items (and row and column heading/index) in
#  the following order:
#    A, b, 6, 7, X, y
#  
#  This is because of the way HTML tables are written and you must write out rows and columns in order.
#  However, you may skip any number of items in the list so long as the order is maintained and you
#  specify where to continue writing.
