Changes

Some minor cleaning up.
 (commit: f310edc)

Solver interface: don't have our methods return an int anymore.
Not quite sure why we ever did return an int in the first place. 
Probably to mimic what the CellML API. Yet, there is no actual need for 
it, not to mention that it results in code that is executed for nothing.
 (commit: 8b87628)

Some minor cleaning up.
 (commit: fcacb8b)

CellML support: make sure that our computeComputedConstants() method can
always be compiled.
Indeed, we couldn’t compile
[OpenCOR]/doc/developer/functionalTests/res/cellml/parabola_variant_dae_ 
model.cellml anymore. Now, all our functional and model files that 
should be compilable are now so.

Some minor cleaning up.
 (commit: 9d6e944)

DAE models: consider them as ODE models that have one or several NLA
systems to be solved (#188 and #536).
 (commit: 327c14e)

Some minor cleaning up.
 (commit: e699699)

CellML support: slight improvement to our computeVariables() method.
 (commit: 432967b)

Slight renaming of some test CellML files.
Also removed a CellML file that is not relevant anymore (since it’s not 
actually an under constrained DAE model).
 (commit: 0a2272d)

Simulation support: slight improvements to our SimulationData class.
 (commit: bfd10c4)

Some minor cleaning up.
 (commit: abbeed5)

Some minor renaming.
 (commit: e060ffc)

Reordered the properties of our KinsolSolverUserData class.
 (commit: 809e6ab)

KINSOL solver: make sure that all our values are finite (#188 and #536).
 (commit: 93f1f0f)

Revert "KINSOL solver: make sure that all our values are finite (#188
and #536)."
This reverts commit 93f1f0f67c8d6240a9b7eff480cf2439b6e81dd5.
 (commit: 6604b26)

Simulation Experiment view: make sure that, from a SED-ML file, we can
open a CellML file which path contains spaces.
 (commit: c45a847)

Added a couple of COMBINE archives that can be used to test DAE models
(#188 and #536).
 (commit: 5c5066f)

Simulation Experiment view: don't reset our NLA solver when further
running a simulation (#188 and #536).
 (commit: 498553d)

Slight update to our known limitations page (#188 and #536).
 (commit: 6978e0f)

Prevent OpenCOR from crashing when a SED-ML file or COMBINE archive
requires a solver that is not present.
 (commit: d13158d)

Slight updates to downloads and what is new pages (#188 and #536).
