What is the best way to compute TL(:,1) and TL(end,:)? #11

When transposing a TL matrix, the rank increases if the first column / last row is not in some range of the generator. It could well be that this can be checked by normalizing the generator (aka proper form) by hyperbolic rotations.

Moreover, generating the first column is an important operation by itself; it is used for example for norm computation, or, more generally, in any column-traversal based operation.

In the Sayed/Kailath literature this goes by the name 'admissible generator'.
