Update DataFrame.to_latex() to have more flexibility

The simple library matrix2latex has a lot of functionality packed into a single function. I think capturing some of those features in the current DataFrame.to_latex() method would make to_latex() much more useful.

The flexibility I am talking about is being able to do these types of things:

• pass in arbitrary environment names
• specify the justification of each column (as well as vertical rules between them)
• natural handling for latex symbols like \infty
• insert captions and labels into the tabular environment

I would like to be able to automatically make certain rows bold. For example, bold the largest values in each column.

Any thoughts on what the right abstraction is for this type of functionality? I’m inclined to think that the user can pass specific rows as well as a function specifying the formatting. (e.g. \bf{}). Then there can be specific options to automatically select on common criteria like max or min.

@KaleabTessera if you have something specific you should like to see probably best opening a separate issue for it at this point
