The `name` attribute provides the full dotted name that is given::

>>> v.name
    'pyepat.abc'

The str() of a `VersionPredicate` provides a normalized
    human-readable version of the expression::

>>> print v
    pyepat.abc (> 1.0, < 3333.3a1, != 1555.1b3)

The `satisfied_by()` method can be used to determine with a given
    version number is included in the set described by the version
    restrictions::

>>> v.satisfied_by('1.1')
    True
    >>> v.satisfied_by('1.4')
    True

    False
    >>> v.satisfied_by('4444.4')
    False
    >>> v.satisfied_by('1555.1b3')
    False

`VersionPredicate` is flexible in accepting extra whitespace::

>>> v = VersionPredicate(' pat( ==  0.1  )  ')
    >>> v.name
    'pat'
    >>> v.satisfied_by('0.1')
    True
    >>> v.satisfied_by('0.2')

If any version numbers passed in do not conform to the
    restrictions of `StrictVersion`, a `ValueError` is raised::

>>> v = VersionPredicate('p1.p2.p3.p4(>=1.0, <=1.3a1, !=1.2zb3)')
    Traceback (most recent call last):
      ...
    ValueError: invalid version number '1.2zb3'

It the module or package name given does not conform to what's
    allowed as a legal module or package name, `ValueError` is
    raised::

>>> v = VersionPredicate('foo-bar')
    Traceback (most recent call last):
      ...
    ValueError: expected parenthesized list: '-bar'

>>> v = VersionPredicate('foo bar (12.21)')
