## Detailed Description

template<class Key, class Value>
struct cereal::MapItem< Key, Value >

A wrapper around a key and value for serializing data into maps.

This class just provides a grouping of keys and values into a struct for human readable archives. For example, XML archives will use this wrapper to write maps like so:

<mymap>
<item0>
<key>MyFirstKey</key>
<value>MyFirstValue</value>
</item0>
<item1>
<key>MySecondKey</key>
<value>MySecondValue</value>
</item1>
</mymap>
