68b129eb96 [1D] Fixed singular Jacobian errors after grid modification 
Modification of the grid can interfere with the way the fixed temperature point
is handled, leading to solver failures. To fix this, the temperature fixed point
is checked and may be recalculated at the start of the solver.

b3a1e1e47c [Cython/1D] 1D solver can be interrupted by ctrl-c 
By calling a pure Python function each time OneDim::eval is called, we can
catch KeyboardInterrupt exceptions and abort the 1D solver loop, returning
control to Python.

Partially addresses Issue 93.

14426bfc86 [1D] Added loglevel argument to control output from save and restore 
Passing loglevel=0 to Sim1D::save or Sim1D::restore will suppress all output
from these functions. The default loglevel maintains the normal level of output.

6ddb55e020 [1D] Fixed a case where the Newton solver could get stuck 
Sometimes, while trying to solve the steady-state problem, the Newton solver
would get stuck in a loop where it couldn't find a suitable damping ratio even
after re-revaluating the Jacobian, causing it to get stuck in an loop where it
would keep re-evaluating the Jacobian at the same point (i.e. without having
made a successful damped step).

This change detects this condition and stops the Newton solver so that the 1D
solver can advance the solution by timestepping before trying to solve the
steady-state problem again.

347029d06a [1D] Added loglevel for saving residual components

refinement is saved to 'debug_sim1D.xml'.

d236358ec6 [1D] Fixed oscillations in grid refinement when pruning is enabled 
Points which are needed to satisfy the 'ratio' requirement are not removed when
pruning. Previously, it was possible for the solver to get stuck in a loop where
the same points were added and removed after successive grid refinements.

351423bcda [1D] Added a new log level for saving intermediate solutions 
Running Sim1D::solve with loglevel set to 7 or higher will now save the solution
after each attempted steady-state solution, after timestepping, and after
regridding to the file 'debug_sim1d.xml'. This can be useful for diagnosing
convergence issues with some problems.

exception to the Cantera error stack now requires explicitly calling
the .save() method.
