|[eigen] TriangularView::solve() interface|

While rewriting part of the tutorial, I noticed that the new
TriangularView::solve() function returns the solution vector, while the
other solve functions pass the solution via one of the parameters. Compare
x = A.triangularView<UpperTriangular>().solve(b);
Was this done on purpose?
The docs on the eigen website  were magically updated, but some of the
latex was not parsed correctly. Am I doing anything wrong? Everything
works fine on my own computer.
Something to perhaps add to the to-do list: a routine to estimate the
condition number of a matrix based on the LU decomposition.
