and made some other minor changes.

that has or overloads the member function.

 that are used for the different process in the staggered scheme

Clang format run on near-the-header lines.

Happy New Year

 in creating of the instances of classes of coupled processes.

 and added a OGS_FATAL checking for the global vector of the solution of
 the previous time step

that is originally for the monolithic scheme.

 from the two classes of coupled term.

[Coupling] Changed the members of the coupled term,

 which only contains the solutions of the coupled equations.

 in one class either with the monolithic scheme or with the staggered scheme.

Added a boolean member to class Process to distinguish the monolithic scheme and the staggered scheme

In some processes (using non-local methods, for example)
the assembly is split in two parts: computation of local
quantities and actual (non-local) assembly (integration)
into the local matrices.

pointer to StaggeredCouplingTerm

passing the coupling term via function argument.

this is already done at start of iteration
