Coding standards

Thanks for the module, it looks great and is just what I am after.

There are some coding standards issues though. For example:
* Some problems with indenting in some places.
* Trailing spaces in some places.
* Some comments are not indented to where they should be.
* Some comments have no space between the // and the comment.
* Comments not always on their own line.
* All binary operators should have a space before and after.

It's a bit picky I know but it helps make the code easier to read.
