nsq module doc

[oej]

• Please add more details on the dependency libraries.
• There are also a lot of spelling errors
• Document return value of function
• Event routes needs to have their own section (like other modules) and not only be mentioned in the introduction
• There is no real explanation of what the transformation actually does, please add some text
• The pseudo variable needs an explanation too, there is obviously some syntax to it with two arguments

Thank you for updating this in good time for the coming release!
