File structure

src: contains all the source (.cpp) files as well as SConscript. Add the new cpp files to the Sconscript.
obj: contains all the compiled files (.o). Can be added to .gitignore as it will be freshly compiled on each system.
include: contains the header (.h) files
app: contains application directories. Each directory should in turn contain: Time folder (such as 0): Contains variable (p, U, etc.) data in OpenFOAM format constant folder : should contain polymesh dir with geometry data inside (in OpenFOAM format) system: Standard OpenFOAM files.
tests: contains output results of all the tests (tests are described in tests.cpp inside src dir).

To run the code:

scons
./out.exe

Note:

Each dir contains a README file for specifics of that dir. Add more information as required.
Template functions need to be completely described in the header files.
Add tests to the tests.cpp. Describe clearly what the tests are doing, what arguments are required and what the user is expected to do.
Add comments whenever appropriate.
Install scons on your system to compile the code. On Ubuntu 16.04, this translates to:

sudo apt-get install scons
