Implement Table methods

[titusfortner]

Things like Table#hashes are very wire call intensive for typically static elements.

A number of Table related methods can be optimized using Watigiri.

Do you have any examples of such methods? Just curious.

#strings - https://github.com/watir/watir/blob/master/lib/watir/row_container.rb#L26
#hashes - https://github.com/watir/watir/blob/master/lib/watir/elements/table.rb#L28
#headers - https://github.com/watir/watir/blob/master/lib/watir/elements/table.rb#L44
#column_header - https://github.com/watir/watir/blob/master/lib/watir/elements/table_cell.rb#L4
#siblings_from_header - https://github.com/watir/watir/blob/master/lib/watir/elements/table_cell.rb#L9

The biggest sticking point here is that there are a lot of different ways that tables can be formatted. What is displayed on the page is not necessarily in the order that it is written in the html due to <thead> and <tfoot> and <tbody> tags, all of which are optional. <th> and <tr> tags are both options for things as well...

Watir gets around this by querying and sorting on the cellIndex attribute of each tr, which is not present when we do an getInnerHtml call for watigiri. I'm not certain the best way around this, other than some complicated brute forcing and/or making assumptions and giving a YMMV disclaimer.

Actually I think #column_header & #siblings_from_header are straightforward now. #hashes & #strings are a crazy number of wire calls.

Makes sense. Thanks!
