in Laplace_equations_routines, generalised Laplace: correction of calculation of effective conductivity
corrected calculation of the sum in the element matrix loop
corrected generalise Laplace in Laplace_equations_routines.f90
update generalised Laplace
update Laplace_equations_routines.f90 and first implementation of extracellular bidomain in Poisson_equations_routines.f90
forgotten file from previous commit
update of not yet finished extracellular bidomain Poisson example
generalised Laplace problem with anisotropic conductivity, final version. And extracellular Bidomain Poisson problem started.
merged my src with upstream
updated Laplace and Poisson equations routines
changes to Laplace_equations_routines.f90 and Poisson_equations_routines.f90
modifications on calculation of dnudxi
changed subroutine coordinate_system_calculate_dnudxi to use interpolated point metrics
Support setting linesearch parameters for PETSc 3.3

Setting OpenCMISS linesearch options had no effect with PETSc 3.3,
as PETSc 3.3 changed the way linesearch options were set and the old
PETSC_SNESLINESEARCHSETPARAMS is no longer available.

This adds wrappers for the new SNESLineSearchBTSetAlpha and
SNESLineSearchSetTolerances routines, and calls them using the
OpenCMISS linesearch settings.
