Remove initialization for steady-state simulations. Fix heat flux
calculations for 3D geometries. Add files for testing BESTEST GC10a case
as well as including new option for Wall Top boundary condition.
Add ability to model planes of symmetry. Fix bug found during BESTEST
GC10a.
Switch to PETSc linear solver library. This offers more flexibility in
the solution method, i.e., users can now select between direct and
iterative solvers, and also accommodates MPI for parallel computing.

This reverts commit b8c8786435ed2a263cf60fe39a2ba8dc20258e76.
Update to Boost 1.55 (only effects geometry routines).
Make weather file a command line argument instead of being part of the
input file.
Add ability to output ficticious ground temperatures as input into
EnergyPlus. Add "Slab Perimeter" surface for reporting both core and
perimeter ground temperatures.
Change output animations to a series of PNG frames for better image
quality and for eventual video encoding.
