Modified GetTimeStep to receive field at each iteration (m_fields->GetPhys not updated at each timestep).
Implemented IO_CheckTime to create checkpoints at specified time intervals.
Removed IO_CheckTime from compressible flow solver regression tests.
Re-added check to make sure that simulation finishes at specified final time.

Fixed minor bug in AssemblyMapDG.
Tidying a couple of routines in PrismExp, ContField3D and CompressibleFlowSystem.

Removed a SOLVERINFO TAG to iniatialise the new advection class. Cleaning up of the class EquationSystem acoording to the previous mentioned modifications. Changed the regressionsTests according to the previous mentioned modifications.

independent and add documentation.
Added documentation for the Riemann solver class.
Fixing overly verbose output in EquationSystem.

Refactored DG code to make solver-level code (mostly) dimension independent.
First working parallel implementation for 2D advection solver (regression
tests to follow).
Lots of code tidying for DG related functions.
Fixed bug so that only the root process outputs timestep information in
IncNavierStokesSolver.

Condensed EvaluateFunction routines to call a single implementation.
Read specific variables from different files and/or expressions in FUNCTIONs.
Updated regressionTest and example XML files to use VAR attribute in FUNCTION.
Deleted unneeded FLD and CHK files in repository.

MemoryManager uses const references instead of non-const references.

Moved EquationSystem classes to two-phase construction to remove solver-specific
references in EquationSystem.
Made all constructors private to enforce use of Factory and therefore ensure
both construction phases are executed.
