Fails to compile on OSX due to illegal array initialisation in material.cpp
The project fails to build due to the following errors:
simulant/material.cpp:62:5: error: array initializer must be an initializer list
defined_properties_(rhs.defined_properties_),
simulant/material.cpp:65:5: error: array initializer must be an initializer list
passes_(rhs.passes_) {
Suggestion was to remove the offending lines and manually copying instead.
