Making language subpackage into a proper package.

- Adding README, setup.py, MANIFEST.in, .coveragerc and tox.ini
- Adding google-cloud-language as a dependency to the umbrella
  package
- Adding the language subdirectory into the list of packages
  for verifying the docs
- Incorporating the language subdirectory into the umbrella
  coverage report
- Adding the language only tox tests to the Travis config
- Adding {toxinidir}/../core as a dependency for the language

+Python Client for Google Cloud Natural Language
+===============================================
+
+    Python idiomatic client for `Google Cloud Natural Language`_
+
+.. _Google Cloud Natural Language: https://cloud.google.com/natural-language/
+
+-  `Homepage`_
+-  `API Documentation`_
+
+.. _Homepage: https://googlecloudplatform.github.io/google-cloud-python/
+.. _API Documentation: http://googlecloudplatform.github.io/google-cloud-python/
+
+Quick Start
+-----------
+
+::
+
+    $ pip install --upgrade google-cloud-language
+    $ # OR
+    $ pip install --upgrade google-cloud-natural-language
+
+Authentication
+--------------
+
+With ``google-cloud-python`` we try to make authentication as painless as
+possible. Check out the `Authentication section`_ in our documentation to
+learn more. You may also find the `authentication document`_ shared by all
+the ``google-cloud-*`` libraries to be helpful.
+
+.. _Authentication section: http://google-cloud-python.readthedocs.io/en/latest/google-cloud-auth.html
+.. _authentication document: https://github.com/GoogleCloudPlatform/gcloud-common/tree/master/authentication
+
+Using the API
+-------------
+
+The Google Cloud `Natural Language`_ API (`Natural Language API docs`_)
+provides natural language understanding technologies to developers,
+including sentiment analysis, entity recognition, and syntax analysis.
+This API is part of the larger Cloud Machine Learning API.
+
+.. _Natural Language: https://cloud.google.com/natural-language/
+.. _Natural Language API docs: https://cloud.google.com/natural-language/reference/rest/
+
+See the ``google-cloud-python`` API `Natural Language documentation`_ to learn
+how to analyze text with this API.
