Add documentation, fix small bugs, improve CustomQuery (#6)

This commit performs the following modifications:

- The library is properly documented in Godoc format.

- The CustomQuery function is made to be a bit more versatile by
  allowing it to also be used standalone (i.e. instead of passing a
  `CustomQuery` as a parameter to the `Query` function, they now have
  their own `Run` method).

- Queries and aggregations can now also be executed using the
  `RunSearch` method. This method is the same as the `Run` method,
  except that instead of an `*elasticSearch.Client` value, it accepts an
  `esapi.Search` value. This is provided for consuming code that needs
  to implement mock clients of ElasticSearch (e.g. for test purposes).
  The ElasticSearch client does not provide an interface type describing
  its API, so its Search function (which is actually a field of a
  function type) can be used instead.

- Bugfix: the CustomAgg function was unusable as it did not accept a
  name parameter and thus did not implement the Aggregation interface.

- Bugfix: the enumeration types are rewritten according to Go standards,
  and the `RangeRelation` type's default value is now empty.

- The golint and godox linters are added.
