Class DoubleToleranceComparer
Double comparer that treats all numbers within tolerance as the same. This comparer doesn't use hash code as it is impossible to create a hashing algorithm that consistently returns identical values for any two points within tolerance of each other. Note that any item that is not within tolerance of other key is set as a new key. This mean that keys are not always whole number in the middle of a range.
