Impact of spatial coarsening on Parareal convergence: Revision

• fixed a bug where domains were set to [0,2] but meshtransfer routines always assume [0,1]. All examples now properly consider domains [0,1]
• fixed a typo in some legends
• added the possibility to plot pseudo spectra and analyze convergence for the higher order upwind finite differences studied by De Sterck et al. 2021

Impact of spatial coarsening on Parareal convergence

Updates v3.0 by fixing some errors in the figure scripts and merging some scripts to avoid duplication.

Impact of spatial coarsening on Parareal convergence

This version of the code produces all the figures shown in the accompanying paper. The release adds the following features:

• tests are converted from nosetest to pytest
• integrators can now be generated using the Dedalus software
• functionality added to compute the pseudo-spectrum and pseudo-spectral radius of Parareal iteration matrices
