rayheader.h:

Namespace AnnularWedgeLagrange:
1) Added static ints for problem IDs, inserted them into a valid problem
id map.

2) Fixed comments

Namespace NavierStokesProblemParameters:
1) Removed a --trilinos_solver, replaced with --solver_type.
2) --solver_type flag is neccessary
3) Moved the documentation of iteration and timing results to a new
function: inline void doc_iter_times(...)

Namespace GenericProblemSetup:
Changes to function inline void setup_solver(...):
1) Instead of passing a boolean to indicate if we want to use trilinos
GMRES solver or not, we pass the solver_type.
2) The function then works out if OOMPH-LIB's own GMRES is required, or
Trilinos Aztec00, or Direct solve (in which case no linear solver is
set).
3) The newton_solver_tolerance() is always set. This is correct.

lagrange_annular_wedge/validate.sh
1) Replaced "--trilinos_solver" with "--solver_type 2"

lagrange_annular_wedge/two_d_annular_wedge.cc
1) Using new NSPP::Solver_type variable where possible.
2) Only document the iteration and timing results if we are not using a
direct solver.
3) Started investigating Tangential flow (--prob_id 12), this currently
does not work, even for direct solve.
4) Using new NSPP::Prob_id == AWL::PID_AW_*** where ever possible
5) Added new functions for imposing tangential flow.
6) In int main(...), we only format the iteration and timing results of
we are not using a direct solver.

NEED TO CHANGE THE VALIDATE SCRIPTS AND FILES FOR OTHER SELF TESTS
modified:   rayheader.h
1) Changed "static int" to "const static int" - everywhere
2) Added problem identifiers for namespace StepLagrange
3) Fixed bug in function "inline void setup_solver(...)"
