[Bug] Excel Add-In: Can't select a Flash Algorithm / Can't configure flash algorithms settings ...

[gastonmora]

DWSIM Excel Add-In ignores Flash Algorithm parameter passed on as the second argument of Flash Calculations function calls.

Also, can't configure Flash Algorithm Settings via the Options->Flas Settings Tab->Configure Flash Algorithm Settings button of the Excel DWSIM Add-In ribbon menu. When clicking the "Configure Flash Algorithm Settings" button, the add-in throws the following error:

System.NullReferenceException: Object reference not set to an instance of an object.
