Fixed h1_summary and h1_summary2 to correctly construct time_bounds values.

h1_summary and h1_summary2 previously used the time_bounds from the last time
value from the last input file when summarizing, suggesting that the field
values were appropriate only over that short time range instead of the complete
time period over which the statistics were calculated. C-LAMP Experiment 1
runs used the previous code, so the time_bounds were incorrect in the
statistical summaries produced. C-LAMP Experiment 2 runs will use this new
code for production of statistical summaries.
