Binary data packing and unpacking.
jpacks 一款强大的二进制结构编解码工具
支持复杂的结构：
e.g.
// 定义结构
jpacks.def('User', {
age: 'uint8',
token: jpacks.array('byte', 10),
name: jpacks.shortString,
note: jpacks.longString,
contacts: jpacks.shortArray('User')
});
var user = {
age: 6,
token: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9],
name: 'ss',
note: '你好世界！Hello World!',
contacts: [{
age: 10,
token: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9],
name: 'nn',
note: '风一样的孩子!The wind of the children!',
contacts: [{
age: 12,
token: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9],
name: 'zz',
note: '圣斗士星矢！Saint Seiya！',
contacts: []
}]
}, {
age: 8,
token: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9],
name: 'cc',
note: '快乐的小熊！Happy bear！',
contacts: []
}]
};
// 组包
var buffer = jpacks.pack('User', user);
// 解包
var user2 = jpacks.unpack('User', buffer);
