-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.

-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.
- - Getters are only generated for message and oneof fields.
- - 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;
