texmex: some cleanup of the cep functions
experiment: load everything
expt, session: moving to norm
session: some improvements to plotting
experiment: added plot quads
updates
session: refactored naive lfc comparison
session: improved quad plotting
experiment: improved interface
added ignore
session, texmexseq: fixed truncation

the ecdf and tcdf line up in the plot.
session: cleaned up truncation, cdf's, plots
session: update quad folds
