Problem 54335. Random Problem14 - Multiply a vector by a scalar of 2

The test suite has been fixed and improved.
Cullen, please take note of the changes. You did include a reference function while editing the problem (that is good). However, it did not pass your test case, which is a warning flag that the problem should not be posted until the reference solution and/or test suite is fixed so that the reference function passes.

Also, please note that this sort of problem has been posted ad nauseam. Please review existing problems on Cody before posting new ones to ensure that yours contain unique aspects.
