cleaning up read_population to mimic builtin's as read.XXX
Got pies_on_map to mostly work and started cleaning up for submission by the end of the weekend.
Working on read.population but have to go back to fix problems in locus.R as well.
Redid the locus.R constructor for all cases and fixed percolated problems from that.  Back onto the manual.
removed as.matrix and made it into to_mv() instead

Getting some tests cleared up
