Add conditionalFormatting() to seealso in createStyle() and addStyle()

[phargarten2]

I couldn't find addStyle() on the conditionalFromatting() page. They are similar functions in that conditionalFormatting() adds styles to the Excel worksheet that are more complicated (based on other cells) than adding a style. To allow users easier access to find these functions, please adjust the #'@seealso in the documentation to incorporate conditionalFormatting(), addStyle() and createStyle() as one family.
