Merge remote-tracking branch 'origin/34-add-support-of-complex-scalar-type' into 73-add-function-to-refine-beam-meshes

This reverts commit 586e1539.

Merge branch '34-add-support-of-complex-scalar-type' of https://gitlab.ethz.ch/mechanics-and-materials/ae108 into 34-add-support-of-complex-scalar-type

- computing generalized eigenvalues is possible for transformed matrices

- uses PETSc's MATSHELL matrix type
