Comment (by ghseeli):

 Alright, I have now added conversions instead of coercions where
 appropriate. Furthermore, I have included some appropriate unit tests. I
 was wondering, should I also include some negative unit tests? As in,
 verify an error is raised when someone tries to instantiate an invalid
 algebra element using an inappropriate symmetric group algebra element?

 Thank you!
