For example, if we have an object ``x1_obj`` that was produced by parsing the ``x1`` in the formula ``"y ~ x1:x2"``, then we conventionally keep track of that relationship by doing:: x1_obj.origin = Origin("y ~ x1:x2", 4, 6) Then later if we run into a problem, we can do:: raise PatsyError("invalid factor", x1_obj) and we'll produce a nice error message like:: PatsyError: invalid factor y ~ x1:x2 ^^ Origins are compared by value, and hashable. cCs||_||_||_dS(N(tcodetstarttend(tselfRRR((s+lib/python2.7/site-packages/patsy/origin.pyt__init__#s  cCsüg}xU|D]M}|dk r;t|tƒ r;|j}n|dkrMq n|j|ƒq W|shdStg|D]}|j^qrƒ}t|ƒdks˘t‚t g|D]}|j ^qŹƒ}t g|D]}|j ^q΃}||j ƒ||ƒS(s!Class method for combining a set of Origins into one large Origin that spans them. Example usage: if we wanted to represent the origin of the "x1:x2" term, we could do ``Origin.combine([x1_obj, x2_obj])``. Single argument is an iterable, and each element in the iterable should be either: * An Origin object * ``None`` * An object that has a ``.origin`` attribute which fulfills the above criteria. Returns either an Origin object, or None. iN(tNonet isinstanceRtorigintappendtsetRtlentAssertionErrortminRtmaxRtpop(tclst origin_objstoriginstobjtotcodesRR((s+lib/python2.7/site-packages/patsy/origin.pytcombine(s   """cCs|j|j|j!S(sgExtracts and returns the span of the original code represented by this Origin.
