Function main::fetch_guard

pub fn fetch_guard<T: Clone>(vector: &Vec<T>, picks: &Vec<usize>) -> Vec<T>

vector.fetch(&my_borrowed_usize_list) will return a vector of your usized picks. Error tollerant and useful for user guided selective statistics, computation of quatriles and building scrolling levels out of 8 bit character bitmaps (maybe?) use one of two ways: genericvector.fetch(&vector_usize_index_picks) or from the function with fetch_guard(&genericvector, &your_usize_picklist)
