it seems like most build systems pass a -DHAVE_CONFIG_H flag to the
compiler which still causes `#if HAVE_CONFIG_H` to be false while it
clearly is supposed to be triggered.
That said, I do not really see a good reason why the inclusion of the
`config.h` file should be guarded in the first place: the file is
guaranteed to always available by proper build systems, and if it was
not included the build either breaks at the linking stage or -- at the
very least -- the runtime behavior of the resulting libraries will be
very awkward.
inconsistent and unnecessary.
this is purely a cosmetic change, the only exception was a function with
the generic name 'split', which was renamed to splitParam to avoid confusion.
On my system I got
```c++
error: variable ‘std::ofstream file’ has initializer but incomplete type
std::ofstream file(fname.str().c_str());
```
This is fixed with this commit by including fstream. Previously,
this include might have happened implicitely.
- Changed interface.
- Read tracerheads (tracer start locations) from file in compute_tof_from_files.
- Initialize tracerheads from wells in compute_tof.
Interface change: solver now requires a linear solver (for the multi-cell blocks only).
Implementation uses new private method assembleSingleCell(), that is a modified copy
of solveSingleCell(). Should refactor.
Also:
- Add use_tensorial_basis parameter allowing run-time choice of basis.
- Remove degree argument from solveTof() method, degree is instead obtained
from parameters in constructors. Modified compute_tof* programs to match.
The limiter is experimental and unfinished, untested work in progress.
Limiter is therefore inactive by default.
Also fixed a minor bug: use_cvi_ was not initialized.
