added hw2
added makeifle

all errors found
init commit of hw3
makefile now works
implemented scheme in timestep.cpp
lax wendroff code is working without bottom topography
trying to put in variable bathymetry

Unfortunately ghost cells aren't working
fixed boundary treatment

I replaced the ghost cell method, which wasn't working, with some if
statments.
added varying bathymetry and moved g,hbar to main
added g and hbar to init
added hbar argument to bottom
added mean bottom topography param

bbar * hbar = actual height of bottom
also outputing exact frames
outputting exact solution to runOutput.py

it is in the entry called frames_exact
fixed indenting. 4 space tabs are conventional for python
made code more pythonic
made PlotFrames more pythonic and faster

got rid of the for loops, and used matplotlib animtation classes
