Disable susplicious function numeric.T.eig.

This function looks in part like a class (i.e. static method), and in part
like an instance method, but neither makes too much sense as it stands.
Reported upstream as sloisel/numeric#61
Will disable the method for now, since it is unusable in its current form.
Disabling it gets rid of a bunch of closure compiler warnings.
