Added background from proposal for porting
Added an overview of the paper layout
Split ported proposal background into sections
Added some more annotations to the proposal sections for porting
Merge branch 'master' into proposal-port
Added all the section files to thesis.rst

1) These will probably change
2) They're all just placeholders at the moment
3) I will probably use the placeholders to reference my scratch imports
from the proposal for now
Gonna actually try writing something for the fitting section today
Fancy build script... will update mkhw
build is now a symlink
Ok, so I wrote *something*
Tracking figures
Ignoring out/ dir in git
Added some notes about cons of the penalty method
Typos, word choice
Small typographical edits and clarifications in penalty method
Added double-spacing to hwdef
Fixed errors in hwdef.tex
Added vanilla least-square section to background-fitting
Use standard build
Add HE quickwrite

This is quickly becoming the hyperelasticity background section of the
paper.  Thus, it will probably require some reorganization later.
