use the correct eigenvector in evp.gsvdtension to output modes. Use 'ms' type search for gsvd. A lot of cleaning up to do here. This includes adding Dirichlet tension methods to...

``` take the single airdom and use its scattered field rep to compute far field at a given single angle, or list of angles. Make a user-friendly scattering.showfarfield which automates...

periodic case: spectral diff non-periodic segment: high-order interpolation. accuracy will suffer a bit, but saves ppl a bunch of annoyance w/ Z, Zp, Zpp for Kress.

``` No way to supress the output figure of [uj,x,y]=p.showmode() I want to take only the data. In addition to that the matrix uj is not a square matrix. How...

``` Since 'fd' is the premier method for low eigenvalues, should identify degeneracies closer than sqrt(eps) (?) and handle separately using local search ('fd' or 'ms'?) to try and regain...

``` Running examples/twodieldiscspointsrcscat.m but with the point source lying inside a dielectric fails because u_inc is only nonzero in the airdom(s). Need to check for this and change u_inc to...
