cons

[Chadtech]

Hi,

This is a function I have in all my Util.elm files nowadays, usually with the name maybeCons. It takes a Maybe and a List and it attaches the value to the front of the list if it exists. In one example, I have an error message I want in my html only if the error exists. I use maybeCons to attach the errorView if the error is a Just Error, but not otherwise. In another instance I need to prepare a list of strings to be displayed like a console read out, and some of the information is stored as a Maybe in the model. I exclude missing information from the read out with maybeCons.

cons was actually already in the module, under the namefoldrValues, and it wasnt exposed.

Best,
-Chad

I like this, and would use it frequently. There were some conflicts, so I rebased it.
