Started replacing wavefd algorithm with an equivalent staggered grid. Still not working
Fixed new FD solution to SH waves and better absorbing boundaries by damping all time panels
Added 1D nonreflexive boundary conditions to SH wave FD
Redefined the Mexican hat source in wavefd to use the cutoff freq instead of wavelength
Using 2 panels instead of 3 in wavefd SH simulation
Added ignore rule for temp image files
Replaced P-SV code in wavefd with the Parsimoneous Staggered Grid algorithm. Not working in water
Updated docstrings in wavefd
Small tweaks to wavefd notebooks
Moved notebooks to their own dir
Outsourced SquareMesh.img2prop to io.fromimage
P-SV simulation unstable. probably error in derivatives of tensions
Updated rules in gitignore
Made lovewave notebook save snapshots instead of using the animation package
Making the notebook of lovewaves nicer
Replaced Cython ndarray declarations with memory views in wavefd
Changed "os the prisms" to "of the prisms"
