A lot of changes are renames for consistency with OGS.

Splitting files, and rename them (dropping mp, p, c prefixes).

Extraction of the create* functions lead to single step initialization
of the Medium, Phase, Component, and Property objects.

Formatting and clang-tidy.
Improve const-correctness.

Remove unneeded Undefined property: The nullptr is probably sufficient
in the PropertyArray, which is an array of pointers, for the property to
be undefined.

Unify value/dValue/d2Value access.

[App] Remove requirement for media ids sequence.

Reorder public, protected, private sections.

Add missing ogs_file_param documentation lines in the code.

due to its std::unique_ptr type instance.

also added two includes to ogs.cpp and ProjectData.cpp due to the forward declaration of the related classes.

The output and project folder are needed for
reading the balance mesh and writing the results
of the balance calculation.

Avoid duplicates.
Remove unused code parts.
Update source code docu.
Use STL algorithms.
Stronger assertions and improve error messages.
etc.

When the python modules are not in the current working directory but
in the projects directory, the user modules would not be found.
Adding project's directory to the python's module path allows to run ogs
from a different directory than the project file.

First forward it to the HT process creation procedure that forwards it
to the class Balance.

This also allows to remove the _geoObjects member from the ProjectData.

Similar functions used by DE are in the DataHolderLib/Project.

New versions of logog do not have an implicit ; after the macros.

Now at the top level of the project's config.

Find a boundary mesh in the list of meshes instead of using GeoObjects
and pass it to the boundary condition creation.

All named geometries are converted to meshes (with
same names).

These meshes will be used by the boundary conditions
and source term constructors.

- Copied ComponentTransport folder
- Renamed ComponentTransport to RichardsComponentTransport
