Implements a transformation into boundaries and is used for boundary handling:

tf = BoxConstraintsTransformationAnyDerivedClass([[1, 4]])
x = [3, 2, 4.4]
y = tf(x)  # "repaired" solution
print(tf([2.5]))  # middle value is never changed
[2.5]

copy/paste this template to implement a new boundary handling transformation
