Adds a setCell overload that takes a bool parameter notify_replace, if this
parameter is true, the replace notification will be triggered as usual,
if it is false, no notification will be triggered. This should keep
backwards compatibility as the default behaviour triggers the
notification.

string type name.

Enables specifying sample materials without a chemical formula or atomic
number in SetSampleMaterial and MaterialBuilder. It is now enough to
specify the scattering and attenuation cross sections and number
density.

Input workspace history needs to be copied to output workspaces. In
the case of groups, where an output replaces an input, the input history
can disappear before we have time to copy it to the output.
