This commit adds support for pybind11 docstrings. It also contains several updates

explained below.

* Add a tutorial to explain how to get started using the package.
* Support PEP-484 annotations.
* Allow type information to be passed to the parser.
* Issue warnings for args that have no documentation.
* Add several configurable options to the parser.
* Fix extraction of multi-line function signatures
* Fix over-loaded functions.

+[MyDocstring](README.md) is a small Python package that allows you to extract and parse docstrings. It suited for building your own documentation system. Docstrings can be displayed as either plain-text, [Markdown](http://commonmark.org/), or [JSON](https://www.json.org/) data.
 
-* Support for Python-code  (support for C-code is planned).
-* Support for [Google-style docstrings](http://google.github.io/styleguide/pyguide.html)
+* Supports [Python PEP484 type hints](https://www.python.org/dev/peps/pep-0484/).
+* Supports [pybind11](https://github.com/pybind/pybind11) docstrings.
+* Supports [Google-style docstrings](http://google.github.io/styleguide/pyguide.html).
 * Produces [JSON](https://www.json.org/), plain-text, and [Markdown](http://commonmark.org/) output for modules, classes, functions, and
   methods.
 
 ## Getting Started
-You can begin extracting and converting docstrings using the command line tool
-`mydocstring` that comes with package. Simply type `mydocstring --help` to see how to use it. 
+If you are interested in building a documentation solution for your own
+project, a good place to
+start is this [tutorial](tutorials/begin.ipynb). This tutorial will teach you
+how to extract and parse docstrings. 
 
-Let's extract the docstring from the following example code and convert it to
-Markdown:
-```python
-def example_function(arg1, arg2=1):
-    """
-    This is an example of a docstring that conforms to the Google style guide. 
-    The indentation uses four spaces (no tabs). Note that each section starts
-    with a header such as `Arguments` or `Returns` and its contents is indented.
-
-    Arguments:
-
-        arg1 (`int`): This description for this argument fits on one line.
-        arg2 (`int`, optional): This description is too long to fit on a
-            single line. Note that it is continued by being indented. 
-
-    Returns:
-
-        `bool` :  Stating the return type here is optional.
-
-        We can continue putting explanations in this section as long as the text
-        is indented.
-
-    This text is no longer indented and therefore not part of the `Returns`
-    section.
-
-    Raises:
-
-        ValueError: This is exception is raised when arg1 and arg2 are equal.
-
-    """
-    if arg1 == arg2:
-        raise ValueError("`arg1` and `arg2` cannot be equal.")
-    if arg1 > arg2:
-        return True
-    else: 
-        return False
-```
-This example code can be found here: [examples/example.py](examples/example.py).
-
-To convert to Markdown, we simply use
-```
-$ docstring examples/example.py example_function --markdown > examples/example_py.md
-```
-The following rendered Markdown is produced: 
-
----
-# example_function
-```python
-def example_function(arg1, arg2=1):
-```
-

-
-
-This is an example of a docstring that conforms to the Google style guide. 
-The indentation uses four spaces (no tabs). Note that each section starts
-with a header such as `Arguments` or `Returns` and its contents is indented.
-
-## Arguments

-    if arg1 > arg2:
-        return True
-    else: 
-        return False
-

-The output above can also be found here: [examples/example_py.md](examples/example_py.md).

-If you are not satisfied with the resulting Markdown, you can provide your own
-[mako](http://makotemplates.org) template
-
-```
-$ docstring examples/example.py example_function --markdown --template customization.md
-```
-Go to [mydocstring/templates/](mydocstring/templates/) to see how to make your own
-template. 
-
-It is also possible to output plain-text, or JSON-data using the flags args
-`--text` and `--json`. Example output can be found here: [examples/](examples/).

+[showcase](#showcase) section that features solutions built on *MyDocstring*.
 
+The project also comes with a command line tool that serves as an example of
+what you can build with the package. See [here](examples/README.md) for learning
+how to use the command line tool and to see some example output.
