uniquetol is a Rust toolbox for isolating unique values in n-dimensional arrays
of imprecise floating-point data within a given tolerance. In the
one-dimensional case, it returns the largest subset in which no pairs of
elements are approximately equal. Here two numbers x and y are said to be
"approximately equal" within an absolute tolerance atol or a relative
tolerance rtol if and only if |x - y| ≤ max(atol, rtol∙max(|x|, |y|)).
This project was inspired by the uniquetol function in MATLAB and NumPy's
unique function in Python.
