Cgmath looking for new maintainers


After a very brief look at the cgmath and nalgebra APIs I don’t see any reason why the dimensioned or uom (I’m the author of this library) unit libraries couldn’t be used. Both can wrap at least f32 and f64 and based on the current functionality of these libraries I don’t think official support (being in the rust-lang-nursery or rust-lang groups) is really necessary. More polish and testing to get the libraries to 1.0 is what’s really needed.
