2d82c78c37 [1D] Retain negative species when retrieving solution state 
This can be useful when debugging issues with the 1D solver.

22537b9493 [1D] Use fixed point temperature closer to unburned gas temperature 
This improves convergence in cases where the domain is too short to achieve full
oxidation and the maximum temperature within the domain is significantly lower
than the flame temperature computed from equilibrium.

5a08cf043f [1D] Make FreeFlame mdot guess pressure dependent 
This gives a better guess for both high and low pressure flames, since velocity
is roughly constant while mass flux can vary by orders of magnitude.

a9293c3168 [1D] Use nonzero initial guess for FreeFlame mass flow rate 
This helps avoids timestepping errors in the first timestep

de8348ecb2 [1D] Use a better default initial grid for FreeFlame 
This initial grid is designed to work well with how the initial profile and
temperature fixed point are set. The only parameter that needs to be
user-specified is the width of the domain.

7484827f2b [1D] Modify fixed temperature selection to keep grid more uniform 
The previous method for setting the fixed temperature point could add a point
very close to an existing grid point, which could then make convergence on the
initial grid difficult.

51e0c9158a [Python/1D] Generalize initial profile generation for diffusion flames 
The calculation of the stoichiometric mixture composition now works for
arbitrary fuel and oxidizer mixtures, including multi-component fuels and fuels
containing oxygen. In addition, it is not necessary to specify any additional
arguments when generating the initial profile.

48c6c6b8ad [Python] Fix full-state (e.g. TPX) properties of PureFluid 
The implementations which come from ThermoPhase expect "X" to mean mole
fractions, but for PureFluid "X" means vapor fraction. No setter is provided
since all three properties cannot be specified simultaneously.

14864e840b Extend NoNorm option for setCoverages to the Matlab toolbox 
Because normalizing the species coverages leads to incorrect Jacobian
calculations, it is sometimes necessary to not normalize the coverages.
As for bulk species mass/mole fractions, this option is currently only
available when passing the coverages as a vector (i.e., not available
for string identifiers).
