MueLu: type issues in LineDetection factory
Created by: lucbv

Description
The MueLu_LineDetectionFactory is using the type Scalar while manipulating coordinates which creates problems when Scalar=std::complex<>.
To fix this the types have been modified to Teuchos::ScalarTraits<Scalar>::coordinateType which ensures that coordinates can be computed on in a sane way.
