Omitempty option for creating maps

[klauspost]

It would be lovely to have an ",omitempty" option to struct members, so they can be omitted if empty similar to the json encoder.

Sounds a good idea! I'll look into it, thanks!

This is merged now. Please refer to the doc for more info: http://godoc.org/github.com/fatih/structs#Struct.Map I'll add this functionality to Fields and Values method too so it's in sync with them. Thanks for the tip again and let me know if you hit problems.
