+Equal returns true iff protocol buffers a and b are equal.
+The arguments must both be pointers to protocol buffer structs.
+
+Equality is defined in this way:
+ - Two messages are equal iff they are the same type,
+ corresponding fields are equal, unknown field sets
+ are equal, and extensions sets are equal.
+ - Two set scalar fields are equal iff their values are equal.
+ If the fields are of a floating-point type, remember that
+ NaN != x for all x, including NaN. If the message is defined
+ in a proto3 .proto file, fields are not "set"; specifically,
+ zero length proto3 "bytes" fields are equal (nil == {}).
+ - Two repeated fields are equal iff their lengths are the same,
+ and their corresponding elements are equal. Note a "bytes" field,
+ although represented by []byte, is not a repeated field and the
+ rule for the scalar fields described above applies.
+ - Two unset fields are equal.
+ - Two unknown field sets are equal if their current
+ encoded state is equal.
+ - Two extension sets are equal iff they have corresponding
+ elements that are pairwise equal.
+ - Two map fields are equal iff their lengths are the same,
+ and they contain the same set of elements. Zero-length map
+ fields are equal.
+ - Every other combination of things are not equal.
+
+The return value is undefined if a and b are not protocol buffers.

+Package proto converts data structures to and from the wire format of
+protocol buffers. It works in concert with the Go source code generated
+for .proto files by the protocol compiler.
+
+A summary of the properties of the protocol buffer interface
+for a protocol buffer variable v:
+
+ - Names are turned from camel_case to CamelCase for export.
+ - There are no methods on v to set fields; just treat
+ them as structure fields.
+ - There are getters that return a field's value if set,
+ and return the field's default value if unset.
+ The getters work even if the receiver is a nil message.
+ - The zero value for a struct is its correct initialization state.
+ All desired fields must be set before marshaling.
+ - A Reset() method will restore a protobuf struct to its zero state.
+ - Non-repeated fields are pointers to the values; nil means unset.
+ That is, optional or required field int32 f becomes F *int32.
+ - Repeated fields are slices.
+ - Helper functions are available to aid the setting of fields.
+ msg.Foo = proto.String("hello") // set field
+ - Constants are defined to hold the default values of all fields that
+ have them. They have the form Default_StructName_FieldName.
+ Because the getter methods handle defaulted values,
+ direct use of these constants should be rare.
+ - Enums are given type names and maps from names to values.
+ Enum values are prefixed by the enclosing message's name, or by the
+ enum's type name if it is a top-level enum. Enum types have a String
+ method, and a Enum method to assist in message construction.
+ - Nested messages, groups and enums have type names prefixed with the name of
+ the surrounding message type.
+ - Extensions are given descriptor names that start with E_,
+ followed by an underscore-delimited list of the nested messages
+ that contain it (if any) followed by the CamelCased name of the
+ extension field itself. HasExtension, ClearExtension, GetExtension
+ and SetExtension are functions for manipulating extensions.
+ - Oneof field sets are given a single field in their message,
+ with distinguished wrapper types for each possible field value.
+ - Marshal and Unmarshal are functions to encode and decode the wire format.
+
+When the .proto file specifies `syntax="proto3"`, there are some differences:
+
+ - Non-repeated fields of non-message type are values instead of pointers.
+ - Enum types do not get an Enum method.
+
+The simplest way to describe this is to see an example.
+Given file test.proto, containing
+
+ package example;
+
+ enum FOO { X = 17; }
+
+ message Test {
+ required string label = 1;
+ optional int32 type = 2 [default=77];
+ repeated int64 reps = 3;
