documentation needs update / OrdinalHinge constructor

[mravanba]

1) In the losses.jl, LogisticLoss is called LogLoss, which is inconsistent with the documentation. 2) Using OrdinalHinge loss will raise an error, because it does not define an empty constructor, needed by the copy method in utilities.

My preference would be for LogisticLoss over LogLoss as this is consistent with what is in EmpiricalRisks.jl and doesn't have the possibility of getting confused with the log function (e.g. as a canonical link for Poisson) On Jan 26, 2016 9:06 AM, "Siamak Ravanbakhsh" notifications@github.com wrote:

Yes, I also prefer the LogisticLoss as a name. But where in losses.jl do you see LogLoss used?

(I've fixed the other error you point out in the most recent commit.)

hmm... you're right about the LogLoss. My local version was not up to date.
