#8 Converting child, subchild etc. blocks to AdaptiveTreeComposites

[Anna Wojtowicz]

This is a ticket from the general NiCE bugs category that I'm copying and pasting over:

I generated new bison.yaml and bison.syntax files, and it looks like the MOOSE team added some new Executioner subblocks: TimeStepper and Predictor.

Both of these should actually be AdaptiveTreeComposites, but they aren't loading up in NiCE as such for some reason.

I addressed this issue so it will correctly read in and convert the Executioner subblocks mentioned, however, this only works for the case of input files which don't have blocks more than one level deep that need to be cast to AdaptiveTreeComposites. (Works for 2D-rodlets and triso, but other examples may not work)

I will leave this open until I can implement a more flexible/robust solution.
