Evaluation methods fail when using a single Material with Properties input

[michaelhoehn]

Description:

This issue basically identifies the applicable differences in Construction creation. In the first instance a user can create a custom construction using two distinct Materials with two distinct Layers that combine to create a single Construction.

The second application suggests a Construction that is comprised of a single Material with multiple properties.

I don't believe either of these is inherently incorrect per se, but I do think the flexibility of these applications does produce something intrinsically different but is still deemed the "same" object.

This introduces a bit of complexity into the code of the LCA engine as it currently iterates over individual properties, rather than any Material containing a list of properties.

Steps to reproduce:

Expected behaviour:

I would expect both types of Material Properties would produce the same value, which is currently not the case.

This seems to be user setup error, which should be documented in the wiki at some point to guide people on best practices. Closing this issue.
