10000 is a bit much...

parser.py

• abstract, supports surf.py
• built in: gauss and usgs surf.py <- parser.py
• generate surface (implements parsers)
• load/plot surface
• plot surface contours
• surface barcode sample.py <- surf.py
• default: show surface (and sample, if provided/generated)
• sample surface
• plot cover/union and contours
• plot lips cover/union and contours rips.py
• no cover plots
• always compute 2/sqrt(3) rips and filter
  • plot both
• lips plot and contours
• lips sub plot and contours
• rips and lips (sub) barcodes

color flag saves an additional file; no recompute.

• decentralize ploting to avoid unnecessary loads
• no plt in main
• implement --rips --union vs. --cover --union
• just hide edges
• no need to re-write json for downsamples
• sample and keep going; no need to reload before rendering
• refactor as contours, topology and util different packages
