estatapi 0.4.0

Major Changes

• Use e-Stat API version 3.0.

Version 0.3.0

Major Changes

• estat_getStatsData() and estat_getStatsList() has been overhauled. Accordingly, each function
  returns the result with different colnames than before. I'm sorry, but this change was inevitable
  to fix bugs like #7... For the details,
  please see this gist.
• Treat most of parameters as formal arguments. Please be careful if you use unnamed arguments.
• Use e-Stat API version 2.1, which is released on Jul 14, 2016.
• estat_getStatsData() automatically repeats fetching records when the records are more than the
  number that can be fetched at one time (=100,000 records). You can stop this behaviour by specifying
  limit or .fetch_all argument.
• Add getDataCatalog(), which finds statistical dataset files (Excel, CSV and PDF) and databases.

Minor Changes

• Show license notice on startup.
