wAllow users to enable or disable tree timer
The new timer is not used by default. It is only enabled if the fdf
file contains the line
UseTreeTimer T

-------------------------------------------------
Feb 5, 2013 Alberto Garcia trunk-432--timing-8
More documentation. timer_off is now recursive
The behavior of 'timer_off' now parallels that of 'timer_report'
regarding the presence and value of the optional argument 'secname'.
modified:
Src/timer.F90
Src/timer_tree.f90
-------------------------------------------------
Feb 4, 2013 Alberto Garcia trunk-432--timing-7
Implemented restricted (section) reports
A report can cover a single section. By default, it prints
also the timings of the first-generation descendants.

Src/timer_tree.f90
-------------------------------------------------
Feb 3, 2013 Alberto Garcia trunk-432--timing-6
Remove hard-coded limit to number of timing subsections
The child array in a given timing section will be resized
if needed.
Added more comments and removed redundant code.
Added timing calls in setup_H0, fft, and matel.

Jan 31, 2013 Alberto Garcia trunk-432--timing-5
Added option to close all outstanding timing sections
The call
call timer('all', 2)
now triggers a complete stop of all outstanding timing sections.
This is useful for clean early termination of programs under some
condition (e.g., when only the setup of H is performed).

Document timer_tree module. Use 64-bit integers for time counter.
Added documentation and hooks to timer_tree to make it almost
completely independent of Siesta.
Added new stand-alone 'die' routine (not in a module) that can
be called from libraries and low-level modules.
The maximum elapsed time without wrap-around in system_clock can
be increased significantly by using 64-bit integers in the calls.
This has been implemented.

Add timing calls for io_dm, io_hsx, and setup_h. Rationalize molmec
'Moleculamechanics' was entering a loop even if no potentials were available.
For large systems this incurred a substantial overhead.
Added timing calls.
NOTE: The maximum elapsed time without wrap-around in system_clock is
only 2147 seconds on PGI systems, including Crays (100 times and 1000
times that for intel and gfortran). Long-running sections might be
wrongly timed. Perhaps the "date_and_time" call can be used to provide
a backup check, but it might be expensive.

Further refinements of timing tree
Added %.
Used walltime instead of cputime, restricting it to the master node.
The "old" (by J Soler) and new timing methods now coexist.
The interim call to timer_report for IterSCF has been deactivated for
now.
