Fixing a bug where conform panics if a field isn't a struct

[gislik]

Conform was choking on a field in a struct which has a type of []byte.

The problem was in the recursive Strings method in which reflection is used to figure out the number of fields in a struct. In this edge case the []byte was passed in a recursive walk of the struct which resulted in a panic when calling ift.NumFields().

This is documented here:

NumField returns the number of fields in the struct v. It panics if v's Kind is not Struct.

My solution is to return early in case the reflected variable is not a struct.

Thank you for your work!
