Given a raw string attribute, try to get the name and type of the
attribute. Constraints:

* The first line must start with @attribute (case insensitive, and
  space like characters before @attribute are allowed)
* Works also if the attribute is spread on multilines.
* Works if empty lines or comments are in between

Parameters
----------
attribute : str
   the attribute string.

Returns
-------
name : str
   name of the attribute
value : str
   value of the attribute
next : str
   next line to be parsed

Examples
--------
If attribute is a string defined in python as r"floupi real", will
return floupi as name, and real as value.

>>> from scipy.io.arff._arffread import tokenize_attribute
>>> iterable = iter([0] * 10) # dummy iterator
>>> tokenize_attribute(iterable, r"@attribute floupi real")
('floupi', 'real', 0)

If attribute is r"'floupi 2' real", will return 'floupi 2' as name,
and real as value.

>>> tokenize_attribute(iterable, r"  @attribute 'floupi 2' real   ")
('floupi 2', 'real', 0)

)r   i  aO  Small container to keep useful information on a ARFF dataset.

Knows about attributes names and types.

Examples
--------
::

    data, meta = loadarff('iris.arff')
    # This will print the attributes names of the iris.arff dataset
    for i in meta:
        print(i)
    # This works too
    meta.names()
    # Getting attribute type
    types = meta.types()

Methods
-------
names
types

Notes
-----
Also maintains the list of attributes in order, i.e., doing for i in
meta, where meta is an instance of MetaData, will return the
different attribute names in the order they were defined.

Read an arff file.

The data is returned as a record array, which can be accessed much like
a dictionary of NumPy arrays. For example, if one of the attributes is
called 'pressure', then its first 10 data points can be accessed from the
``data`` record array like so: ``data['pressure'][0:10]``


Parameters
----------
f : file-like or str
   File-like object to read from, or filename to open.

Returns
-------
data : record array
   The data of the arff file, accessible by attribute names.
meta : `MetaData`
   Contains information about the arff file such as name and
   type of attributes, the relation (name of the dataset), etc.

Raises
------
ParseArffError
    This is raised if the given file is not ARFF-formatted.
NotImplementedError
    The ARFF file has an attribute which is not supported yet.

Notes
-----

This function should be able to read most arff files. Not
implemented functionality include:

* date type attributes
* string type attributes

It can read files with numeric and nominal attributes. It cannot read
files with sparse data ({} in the file). However, this function can
read files with missing data (? in the file), representing the data
points as NaNs.

Examples
--------
>>> from scipy.io import arff
>>> from io import StringIO
>>> content = """
... @relation foo
... @attribute width  numeric
... @attribute height numeric
... @attribute color  {red,green,blue,yellow,black}
... @data
... 5.0,3.25,blue
... 4.5,3.75,green
... 3.0,4.00,red
... """
>>> f = StringIO(content)
>>> data, meta = arff.loadarff(f)
>>> data
array([(5.0, 3.25, 'blue'), (4.5, 3.75, 'green'), (3.0, 4.0, 'red')],
      dtype=[('width', '<f8'), ('height', '<f8'), ('color', '|S6')])
>>> meta
Dataset: foo
    width's type is numeric
    height's type is numeric
    color's type is nominal, range is ('red', 'green', 'blue', 'yellow', 'black')
