Code/rows and columns

[blythechan]

Issue

• BBCode Tag: Rows & Columns #41

Requirements Met

• Implement row and column bbcode

Notes

• Originally, I was passing two classes together in a single attribute for columns; however, once baked or cooked the columns would have no class assigned whatsoever. I looked into this as much as I could and found that the classes were kept throughout the processing logic. I am unsure what causes it to drop the classes when there are more than one. I switched my approach by using a data parameter.
• Default of "1" applied.
