Change DataFrame to_sql's first parameter to something more descriptive
This is a high-level suggestion.

`DataFrame.to_sql(name, con, ...)`

It's not intuitive if `name` means name of database or name of table in database.

I think something like `table_name` or `tablename` would better explain what `name` is.

Yes, I know I can Google it every time and eventually after Googling it so many times I'll eventually learn it... but isn't the point to make it intuitive and easy-to-use? Others might not have this same minor issue.
