Created outline for python-script.
Now filtering input according to date.
Created prototype for log_sum_c-function. Fixed bug in log_sum_filter causing only the dates to be written to the filtered source list.
Implemented log_sum_c().
Implemented log_sum_2().
Implemented log_sum_r().
Implemented log_sum_F().
Implemented log_sum_t().
Added filtering method based off which HTTP-query one wishes to analyse.
Implemented log_sum_f(), I think.
Now reading filename as command line argument. Bit of a hack, where a bit is about the size of the sahara-desert.
Started on the awk part of the assignment. Can accept arguments, read from the correct dates and display correct number of results. Also implemented funktionality for argument c.
Renamed log_sum_date.awk to log_sum_time.awk.

Fixed a bug in log_sum_c.awk where the result limit did not work properly.
Removed function tst() from log_sum_c.awk since it wasn't used.
log_sum_t() now prints the IP to which the most bytes have been sent in total, rather than the highest amount in one transmission. Also optimized log_sum_d slightly by looking up the numeric representation of the month in a loop-up table rather than with a loop.
Implemeneted support for flag 2. Due to problem with passing arguments in awk the syntax s=1 needs to be used to call 2.
Started working on flag r. It doesn't work properly yet.
Implemented supprt for r.
All flags are now implemented and seems to be working correctly.
Merge branch 'dv1457_1_awk' into dv1457_1
