Trying to modify Kraw 2D
Newton cleanup; Krawczyk output format
Atahualpa's algorithm for finding first collision
Fixed the Krawczyk division by thin zero error
Fixed the power in AutoDiff
Krawczyk 2D works but at small initial intervals - examples in notebook; Newton 2D started
newton2d passes most Moore tests
newton2d further tests; finds zeros with issues
2D bisection notebook
