Add timer tree output and associated parameters

New parameters output_initialise_timer_tree and
output_timer_tree_every control output of a new "timer tree diagram"
to standard output for the Initialise and Evolve timer trees
respectively.  These diagrams indicate:

1. the value of each timer;
2. the percentage of the given tree taken by each timer;
3. which timers are contained in which other timers;
4. any untimed code

for any timer which takes more than 1% of the tree time.
