Refactor rank calculation function in Trace

Removed uneccessary comments and rearranged the order of types in the parameters within the rank calculation function. Further, the array returned was reformatted for improved readability. The process of incrementing the value of 'sameMetricValueCount' was also changed to the more standard unary operator (++$var).
