Add proper Start and End procedures.

[martindsouza]

With this we can track how many times a procedure is called and how long it took to run. Based on this we can then calculate the average run time for a procedure etc. This will involve modifying the template as we'd want developers to use the new start/end procedures instead of logger.log('START'...);

May require modifying the timing procedures to store timing in its own column so that we can perform calculations on average procedure runtime etc. See #1 for more info on this.
