Ambiguous concept definitions are not highlighted

[adrianffletcher]

When there are two concepts defined with the same name and both are imported into an Ergo file it is not clear which one is being used and there is no warning or error message produced by the compiler.

The attached archive file (which needs to be renamed back to a .cta file to be used) gives an example of this where there are two LineItem concepts defined and it is not clear if the code should compile or not.

There should at minimum be a warning generated by the compiler if it needs to choose between two different concept definitions and consideration should be given to requiring explicit disambiguation in this case.
