You have a two vectors, a and b. They are monotonic and the same length. Given a value, va, where va is between a(1) and a(end), find the a(n) and a(n+1) that flank it. Now interpolate the value, vb, such that it is proportionally between b(n) and b(n+1).
Note that va can land exactly on a value of a as well.

The tests do not check va equal to a(1) or a(n).

Test cases added to include for corner values as well.

The test is broken. The question statements gives that "va" is between a(1) and a(end), but the last test gave va = a(1).
