This class can measure the time passed between execution moments.

It can start a timer in a given moment and take note of the time that elapsed until another moment after having executed some PHP code.

Each moment is associated to a given text label. The class also records the RAM amount used by the current PHP script when it records the elapsed time for a given moment.

The class can return all the recorded moments as a single array or JSON object.
