make phase field examples more explicit

[wd15]

Update the phase field examples to be more explicit. Remove the factory methods for building equations and have them explicitly defined in the input scripts. Also state the variables in the input files rather than having them as separate classes. Make some of the examples have inlined variables within the input scripts.
