Ecto.Enum.cast_value/3

[cjbottaro]

@josevalim Is this what you meant by adding a function to Ecto to make this easier
phoenixframework/phoenix_html#461 (comment)

Let me know if this is what you were thinking or any changes need to be made!

Originally I was thinking to define cast_value/3 in terms of cast/2, but it felt "heavy" having to call init/1 and figuring out the options with which to call it. But maybe the "heaviness" isn't as bad as I imagine?

[cjbottaro]

Ahh, I figured out that you can get the params via the __changeset__() function. So now cast_value/3 is defined in terms of cast/2.

I am happy! Let's see if other maintainers agree too!

[cjbottaro]

One really nitpicky thing... should the function be called cast_data instead of cast_value? data seems to be more inline with the terminology used throughout the file.

I am happy with cast_value but let's see if someone has a different opinion.

[greg-rychlewski]

I like cast_value. It seems more inline with the other function names.
