Description

It is sometimes useful to for the presence of a double within a given tolerance.
For example, does this double[] array contain 3.054 +/- 0.001?

The patch attached adds new methods which use the DoubleRange test elements of
an array:

ArrayUtils.indexOf(double[] array, double valueToFind, double tolerance)

ArrayUtils.indexOf(double[] array, double valueToFind, int startIndex, double
tolerance);

ArrayUtils.lastIndexOf(double[] array, double valueToFind, int startIndex,
double tolerance);

ArrayUtils.contains(double[] array, double valueToFind, double tolerance);
