Adds a class library from which files can be loaded.

The `add()` method registers a named library configuration to your application, and is used
to allow the framework to auto-load classes on an as-needed basis.

### Adding libraries to your application

In Lithium, libraries represent the broadest unit of class organization in an application,
and _everything_ is a library; this includes your application, and the Lithium framework
itself. Libraries can also be other frameworks, like Solar, Zend Framework or PEAR, or
Lithium plugins, which are simply libraries that follow the same organizational standards
as Lithium applications.

By convention, libraries are placed in the `libraries` directory inside your application, or
the root `libraries` directory at the top level of the default distribution (i.e. the one
that contains the `lithium` directory), however, you can change this on a case-by-case basis
using the `'path'` key to specify an absolute path to the library's directory.

@param string $name Library name, i.e. `'app'`, `'lithium'`, `'pear'` or `'aura'`.
@param array $config Specifies where the library is in the filesystem, and how classes
should be loaded from it.  Allowed keys are:
- `'bootstrap'` _mixed_: A file path (relative to `'path'`) to a bootstrap script that
should be run when the library is added, or `true` to use the default bootstrap
path, i.e. `config/bootstrap.php`.
- `'defer'` _boolean_: If `true`, indicates that, when locating classes, this library
should defer to other libraries in order of preference.
- `'includePath'` _mixed_: If `true`, appends the absolutely-resolved value of
`'path'` to the PHP include path. If a string, the value is appended to PHP's.
- `'loader'`: An auto-loader method associated with the library, if any.
- `'path'`: The directory containing the library.
- `'prefix'` _string_: The class prefix this library uses, i.e. `'lithium\'`,
`'Zend_'` or `'Solar_'`. If the library has no global prefix, set to `false`.
- `'suffix'` _string_: Gets appended to the end of the file name. For example, most
libraries end classes in `'.php'`, but some use `'.class.php'`, or `'.inc.php'`.
- `'transform'` _\Closure_: Defines a custom way to transform a class name into its
corresponding file path.  Accepts either an array of two strings which are
interpreted as the pattern and replacement for a regex, or an anonymous function,
which receives the class name and library configuration arrays as parameters, and
returns the full physical file path as output.
- `'resources'` _string_: If this is the default library, this maybe set to the
absolute path to the write-enabled application resources directory, which is used
for caching, log files, uploads, etc.
@return array Returns the resulting set of options created for this library.
