Description: # data-mapper
        A declarative data mapper
        
        ## Description
        
        Most projects work with different representations of the same data.
        The code that is written every time to morph data between its representations
        is mostly very repetitive. More over, it is always a deposit of bugs and issues
        which requires a developer or tester to unit-test it.
        
        This package is an attempt to solve these problems... well, at least the most
        common ones.
        
        And to make a developer job easier it is primarily designed to be used
        in declarative fashion: describe what you want and get it right after.
        
        ## Use Cases and Features
        
        Here are examples of the most common use-cases and features: 
        
        ### Different Naming Schemes
        
        This mapper looks for properties `first_name` and `last_name` in the data.
        For property `first_name` it tries to resolve it by the first key 
        `'first_name'`, if not found it tries the second key `'name'`.
        The similar process goes for property `last_name`.
        
        ```python
        from data_mapper.mappers import Mapper
        from data_mapper.properties import Property
        
        class PersonMapper(Mapper):
            first_name = Property('first_name', 'name')
            last_name = Property('last_name', 'surname')
        
        mapper = PersonMapper()
        
        assert mapper.get({
            'first_name': 'Ivan', 
            'surname': 'Bogush',
        }) == {
            'first_name': 'Ivan', 
            'last_name': 'Bogush',
        }
        
        assert mapper.get({
            'name': 'Ivan', 
            'surname': 'Bogush',
        }) == {
            'first_name': 'Ivan', 
            'last_name': 'Bogush',
        }
        ```
        
        This use-case has a story :)
        > It was the first issue I wanted to solve in my other project. I had different 
        naming schemes in different data sources, and in my databases. All of them used 
        different names for product categories: 'categories', 'category', 'categoryId'.
        I found it very boring to write repeatable code to convert the same data.
