Merge consistency checking processes?

[jctophefabre]

Consistency checking is performed in the framework when simulation is instanciated, and is also performed on-the-fly in OpenFLUID Builder.
If possible, the two consistency checking should be merged into a single process in the framework, used at simulation instanciation or on-the-fly, essentially based on descriptors.
Introduce consistency error codes with parameters, allowing to generate standardized warning/error messages, either in CLI or UI apps.
