Martin Diehl b1ba64e6af understanding floating point precision
double can use 16 or 17 significant figures
- if the leading number is high (above 5 or so), only 16 figures are
significant.
- a trailing 1 is never significant

Martin Diehl 85735605f8 more flexibility for the L in the load case
Note that mixed boundary conditions for L introduce an ambiguity.
Consider:

L = [[1.0, x, x],
     [  0, 0, 0],
     [  0, 0, 0]]
P = [[x, 0, 0],
     [x, x, x],
     [x, x, x]]

What we need is F^(n+1)=F_dot^(n+1) x Delta_t, where F_dot^(n+1) is
F_dot^(n+1)_ij = L_ik F^n_kj.

So component F_11 has contributions from L_12 and L_13. We first assume
L_12=L_13=0 and then choose F^(n+1)_12 and F^(n+1)_13 to get
P_12=P_13=0. This implicitly gives a solution for L_12 and L_13, which
is however only one out of infinitely many.
