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