logfmt for zap

 This package implements logfmt for zap
 .
 Limitations: It is not possible to log an array, channel, function,
 map, slice, or struct.
 .
 Namespaces are supported. If a namespace is opened, all of the keys
 will be prepended with the namespace name. For example, with the
 namespace foo and the key bar, you would get a key of foo.bar.
