Construct a :class:`ChowCycle`.
INPUT:
- ``parent`` -- a :class:`ChowGroup_class`.
- ``v`` -- a vector in the covering module, that is, with one
entry for each cone of the toric variety.
- ``check`` -- boolean (default: ``True``). Verify that ``v``
is in the covering module. Set to ``False`` if you want to
initialize from a coordinate vector.
TESTS::
sage: P2 = toric_varieties.P2()
sage: A = P2.Chow_group()
sage: from sage.schemes.toric.chow_group import ChowCycle
sage: ChowCycle(A, (0,1,2,3,11,12,13), check=False)
