4a8f318905 Listtypes (#714) 
* mat: Add missing types to list test

With the recent additions of Diagonal and TriBanded, there were some matrix types that were not added to the list of testing types. There were additionally some older types that had been left out. This PR completes the set of types, their transposes, and their basic counterparts to the set of matrices. Changes are made to the makeNew etc. routines in order to support this.

This also changes the behavior of Triangle to return the embedded TriKind even if the matrix IsZero (before we intentionally corrupted the value). We document that the value cannot be trusted, so it shouldn't matter, but this way is simpler, and allows the TriKind to be used in list_test to specify matrices with different TriKind.

Fixes #266

This should probably use a rich error strategy, but we can leave that for
when the Go error handling experiments are more fully developed.

a5c280a104 lapack/gonum: check lda after workspace query return in Dorgqr 
Dorgqr is queried at several places in Dgesvd for workspace size with
varying arguments. With the current code it is impossible to pass
the lda check. The reference gets around this because it's column-major
and the number of rows is the same for each call.

a8f1562992 graph/testgraph: new package for testing graph implementations 
Currently variant line types do not work the same way as they would with
a slice of edges because access to a []graph.Edge also allows the
elements of that slice can be type asserted to richer types like
graph.Line or graph.WeightedEdge for example. This cannot be done with
the API as is stands with the iterator-holding edge being down graded
from one of the richer types.
The problem can be avoided by either making graph.WeightedLines also
satisfy graph.Lines (same for edges), or by down-typing the edges in the
non-weighted edge return methods for the graph implemetations.
