first remove (generate_traversal_graph):
# does: if only one traversal, just use it if len(traversals) <= 3: graph[0].add((1, (0, 0))) graph[1].add((2, (0, 0))) return graph, traversals
and (traverse_recursive):
elif len(critical_traversals) == 1: # if only one critical event is found …
then fix errors

At the moment no hyperbola is returned, because cell.steepest_decent() returns no steepest decent found, in cases where steepest decent is no longer in cell.

adding points through input coord onClick often results in wrong point position

Anton Begehr, Fu Berlin, Bachelor Computer Science, Prof. Rote, 2018, etc

Ex.: https://abegehr.github.io/frechet/?p=(-1_1)(4_1)(-1_1)(4_10)&q=(0_0)(0_5)

The in the input coord, the scaling for x- and y-axis is not equal.

https://abegehr.github.io/frechet/?p=(6_5)(6_16)(6_6)(-7_17)(6_16)&q=(8_6)(-4_6)(6_16)
classical critical event at (~38.0, ~17.7) shows height 9.9, should be 10.0

example: http://localhost:3000/?p=(3_4)(6_4)(3_4)(6_4)(3_4)&q=(3_2)(6_3)(6_5)(3_6)

extend backend algorithm to solve degenerate inputs: multiple possible critical events with same epsilon

example https://abegehr.github.io/frechet/?p=(1_0)(4_0)(2_1)&q=(0_1)(0_4)(2_3)
shows inf for sq_reci_slope
