= Yaml2Csv

Transform YAML file into CSV and backwards. CSV files contain
triplets [path, key, value]. For example:

    path1:
      path11:
        key11a: value11a
        key11b: value11b
      path12:
        path121:
          key121a: value121a
    path2:
      key2a: value2a
  
Will be converted into:

    path1/path11,key11a,value11a
    path1/path11,key11b,value11b
    path1/path12/path121,key121a,value121a
    path2,key2a,value2a

YAML source files should contain only hashes and string values. While non-string 
values (i.e. arrays, booleans) are allowed, they will be treated as strings 
thus their original format will be lost.

== Usage 

=== As a gem

In your Gemfile:

    gem 'yaml2csv'

In your code:

    output_string = Yaml2csv::yaml2csv(input_string)
    output_string = Yaml2csv::csv2yaml(input_string)

=== rake task

Convert file.yml into CSV format:

    $ rake yaml2csv:yaml2csv INPUT=file.yml OUTPUT=file.csv

Convert file.csv into YAML format

    $ rake yaml2csv:csv2yaml INPUT=file.csv OUTPUT=file.yml
