Function sdfgen_lib::get_closest

pub fn get_closest(
    active: &Vec<[u32; 2]>, 
    value: &[u32; 2], 
    second_pass: bool
) -> [([u32; 2], u32); 3]

Finds the closest coordinate in the give coordinate list active. Returns and array of the size of 3. If secondpass is not enabled these will all be the same ( the closest coordinate). second_pass enables the search of three closest values, instead of just one.
