Bind Query Parameter to an struct

[jkroepke]

Hi there!

I would be great, of binder would support to bind a query parameter to an struct.

Example:

type query struct {
	a struct {
		a string
		b string
		c string
		d string
	} `query:"a"`
}

and a[a]=b would map to query.a.a. This would be helpful, if my own application includes structs from 3rd party vendors, where I cant attach additional query metadata.
