Review the algorithm and the table parser js code

[duboisp]

• Rewrite in a way that it do not use processing time if is not needed/requested
• Find a way to identify summary group faster, that could be useful to adapt table on mobile device
• Separate the actual table parse in 2 part if possible, where the first is just assuming and move forwared with the complex table structure. then the second portion will do the hard validation with the double check
• Considerate to save the parsed data information in the DOM instead of using jQuery data.
