fix undefined/NaN issues in region
using is-triangle tests in region divide
pass in regions and max separately
compute slope outside, seems to work better
switched to a point buffered model
it actually appears to work!
emit best events
show the iteration
simplified recurrence cases
refactored with region next() so that calling search next() is 1:1 with calling the test function
updated the examples
call fn() inside the initial fake quad region
failing test for 4d center
1-d example has too low dimensionality
center actually works fine
partial fix for higher dimensions
center test failing in 4d
somewhat updated
