test trig potential error growth
add project file
move files to folders
add setup.py
fix package

installation now works.
I also changed the class names to caps, since apparently that's the
standard...
change class names in test
add Hamiltonian class

plus CM2 and CM4 solvers for Hamiltonian class
add CM6 and CM8
plot evdt for CM6 as well
add useless stuff to ignore
add example for getting stability region
add Euler Extrapolations
reformat ode.py
finish reformatting ode.py
add SSPRK104, and alternate EE4

still testing stability thing.
update stability.ipynb
add get_stability_region function
bugfix: EE4 was not returning solution
add subroutine to generate class methods dynamically
move EE generator to base_ODE
