Tweaked explanation of output for executed events

The event status is <I>E</I> when an event is executed, and 

is <I>D</I> for an event that is detected, while <I>DF</I> is for a detected

event that is also the earliest (first) event at the low temperature.

The time margin is the ratio of the high temperature time in the current

<P>The time margin is the ratio of the high temperature time in the current

basin to the stopping time. This last number can be used to judge

whether the stopping time is too short or too long (see above).

<P>On lines for executed events, with status <I>E</I>, the global event number is

incremented by one, and the timestep, clock, local event number, 

and energy barrier match the last event with status <I>DF</I> in the 

immediately preceding block of detected events.

The event status is {E} when an event is executed, and 

is {D} for an event that is detected, while {DF} is for a detected

event that is also the earliest (first) event at the low temperature.

The time margin is the ratio of the high temperature time in the current

basin to the stopping time. This last number can be used to judge

whether the stopping time is too short or too long (see above). 

On lines for executed events, with status {E}, the global event number is

incremented by one, and the timestep, clock, local event number, 

and energy barrier match the last event with status {DF} in the 

immediately preceding block of detected events.

The NEB statistics are written to the file specified by the {neb_log}

keyword. If the keyword value is "none", then no NEB statistics are

printed out. The statistics are written every {Nevery} timesteps.  See
