Write a program that parses Apache Common Log Format log files and produces a report. Your program will take the pathname of the log file to use as a command line argument. The report will always output the following items:

Filename of the log file.
Total number of bytes transferred
The other report items will only be output if the appropriate command line arguments are specified:

-h: Print a help message and exit without a report. The message should look something like the following output. You can add a longer description of the program's functionality.
ApacheReport: An Apache Log Parser

	-h:	Print a help message and exit without a report.
	-i:	ASCII histogram of IP addresses.
	-u:	ASCII histogram of URLs.
	-s:	Sorted list of HTTP status codes, with percentages.

	apachereport [-h] [-i] [-u] [-s] logpath
-i: ASCII histogram of IP addresses
Output consists of two columns, the left containing IP addresses, and the right containing a histogram showing the number of accesses from that IP address. The histogram is constructed as a string of hash marks.

-u: ASCII histogram of URLs
This option is similar to the previous option, which the difference that URLs have widely varying lengths, requiring you to truncate some of them to make the histogram readable. Add a vertical bar character at the end of a truncated URL so the reader knows what happened.

-s: Sorted list of HTTP status codes, with percentages of URLs that resulted in each status code, which should be printed like this example:
HTTP Status Codes Summary:

200: 90%
301: 8%
401: 1%
404: 1%

Bytes transferred: 4338917
Options can be specified in any order. An invocation of your program could look like any of the following examples:

$ ./apachereport cit383/test_log
$ ./apachereport -u test_log
$ ./apachereport -u -i /var/log/test_log
$ ./apachereport -s -u ~/test_log
$ ./apachereport -i -s -u ../log/test_log
If incorrect command line options are specified, .e.g. a non-existent option like -f or no filename being specified, then the program must print a help message that explains how to run the program and exit.
