The bestGuess option will try to determine which columns should be used.

If there are 3 columns and the first column is a sequential number starting at '1' it looks like this is a line number, we will ignore it.

If there are many columns maybe we have a format like X1, Y1, X2, Y2, ... in this cases if one column on two is a monotone series we will parse it correctly.
