Create a new Parameter object.
:param name: The name of the parameter. This will become an instance
member of the plugin object to which the parameter is
applied, so it must be a valid python identifier. This

:param kind: The type of parameter this is. This must be a callable
that takes an arbitrary object and converts it to the
expected type, or raised ``ValueError`` if such conversion
is not possible. Most Python standard types -- ``str``,
``int``, ``bool``, etc. -- can be used here. This
defaults to ``str`` if not specified.
:param mandatory: If set to ``True``, then a non-``None`` value for
this parameter *must* be provided on plugin
object construction, otherwise ``ConfigError``
will be raised.
:param default: The default value for this parameter. If no value
is specified on plugin construction, this value
will be used instead. (Note: if this is specified
and is not ``None``, then ``mandatory`` parameter
will be ignored).
:param override: A ``bool`` that specifies whether a parameter of
the same name further up the hierarchy should
be overridden. If this is ``False`` (the
default), an exception will be raised by the
``AttributeCollection`` instead.
:param allowed_values: This should be the complete list of allowed
values for this parameter. Note: ``None``
value will always be allowed, even if it is
not in this list. If you want to disallow
``None``, set ``mandatory`` to ``True``.
:param constraint: If specified, this must be a callable that takes
the parameter value as an argument and return a
boolean indicating whether the constraint has been
satisfied. Alternatively, can be a two-tuple with
said callable as the first element and a string
describing the constraint as the second.
:param merge: The default behaviour when setting a value on an object
that already has that attribute is to overrided with
the new value. If this is set to ``True`` then the two
values will be merged instead. The rules by which the
values are merged will be determined by the types of
the existing and new values -- see
``merge_config_values`` documentation for details.
:param aliases: Alternative names for the same configuration point.
These are largely for backwards compatibility.
:param global_alias: An alias for this parameter that can be specified at
the global level. A global_alias can map onto many
ConfigurationPoints.
