Material data files

To define material properties:
- either use functions from m6 material file (only a subset of all options is supported, see below)
- use built-in functions from Material class, in this case the material reference in the project file must have the name:
built-in:<nr>
Example:
<!--List of all materials used in this construction-->
<Materials>
<MaterialReference name="My material">built-in:2</MaterialReference>
</Materials>
This will make the solver use the built-in material data set with index 2 (see Material
class).
OpenHAM supports a subset of the material functions used in DELPHIN when providing material data files.
Moisture-tight materials have to be flagged as such by VAPOR_TIGHT or WATER_TIGHT flags (see material model).
Required parameters:
- LAMBDA_DRY
- CET
- RHO
Functions:
- moisture retention function thetal(pc) as spline
- liquid conductivity lgKl(thetal) as spline
- vapour permeability lgKv(thetal) as spline or parameter MEW
