* fixed problems with fxing unsign ints
   main.cc, transport_dg.cc, mesh.cc
* cleanup in darcy_flow_mh.cc, mesh.hh
* added support for selection description in Latex documentation
* CMakeLists.txt - introduced definition HAVE_SINCOS  - workaround for clang on cygwin
* fixed return in field_constant_impl.hh
* fixed semchem_interface.cc - probably wrong setting of mesh pointer
commit for backup, test_20 fails during iterative solution, Error in function boost::math::tools::toms748_solve<d>: Parameters a and b do not bracket the root: a=0
formal neccessery corrections in header files
Simulation of sorption described by linear and langmuir isotherm seems to be functional, at least with parameters used in test 20. Limmited solubility is not involved now and the solver toms748solve is used instead of interpolation.
