An ordered sequence of anonymous map nodes.

node	A YAML node can be one of three types: list, scalar, map. Every node may optionally have a class.

# comment

# list An ordered sequence of zero or more nodes. 

   # Nodes are included by reference, 

   # thus they may be part of more than one list or map.

men: [tester1, tester2]

women:

  - tester3

  - tester4

# scalar: An ordered sequence of zero or more bits. 

   # Where bits are an atomic construct able to have a value of one or zero.

# map(key, value)

# An un-ordered sequence of zero or more (key, node) tuples 

# where the key is unique within the sequence.

- {name: lqwangxg, career: it}

- name: tester1

  career: test  

#key： A sequence of zero or more characters.

#class: An opaque object that has a serialization which complies with the class production.The serialization model adds an anchor attribute to every node, and introduces the reference node. The reference node advertises an anchor to indicate the repetition of a node previously encountered.

#anchor An additional attribute added to each node that provides for identification of the node within a given node sequence. Only nodes which could be referenced further in the sequence must be given an anchor. It is not necessary that the anchor is unique.

# reference  An additional node type consisting of an anchor which is used to indicate the repetition of the node with the same anchor most previously encountered.

#Block Scalar

first: |This is a block scalar,    with significant

       |whitespace, and the use of " @, etc.

       |The \ is used to signify the end of the block.

       |     Whitespace    *is*    significant.

       \

#Quoted Scalar

second: "Escape sequences can be used 

             to removed or \ add white\

             space, \\ and \" must be escapted"

#Binary Scalar

binary: [R0lGODlhDAAMAIQAAP//9/X17unp5WZmZgAAAO

desc: "A binary scalar uses the base64 encoding. 

         Base64 strings are a sequence of base64 characters intermixed with 

         whitespace which is ignored by the base64 processor. 

         An additional constraint is that no more than 76 sequential characters

         are allowed without at least one intermediate whitespace character. "
