This is a test to evaluate your HTML and basic python skills. Take your time - you are free to ask people about how some bits work.

Situation:
The company is developing a HTML <table> generator. Your job is to make a class for this <table> generator.

Example input:
studentid.txt
Student Name, Student ID, Email, Country;
Alice, 555, rihbo@fjnfw.com, Hong Kong;
Billy, 52266, uih@uhfuewinf.com, America;
Wheatley, 3.14, nyan@cat.com, Space

The first line is the header - it defines what fields are there.
The numbers of

Handling erroneous output:
If the row has less items than the header: fill the missing items with a space (&nbsp;)
If the row has more items than the header: raise a ValueError with the message "Too many values in row, content was {ROWCONTENT}"

Expected output: (All the results should be aligned center, this effect is not shown in the following output)
Please output the result as raw, complete HTML.
No title is necessary.

================= START OF EXPECTED OUTPUT =================

studentid.txt <- Header 1, Aligned center, Bold, Underline
-------------------------------------------------------------
| Student Name | Student ID | Email             | Country   |
-------------------------------------------------------------
| Alice        | 555        | rihbo@fjnfw.com   | Hong Kong |

-------------------------------------------------------------

Size of file: FILESIZEHERE
MD5 Checksum of file: MD5CHECKSUMHERE

================== END OF EXPECTED OUTPUT ==================


All functions inside the generator class must be well-documented, including usage, parameters, and expected return result.

Hints:
How to get MD5 Checksum of a file:

import hashlib

def md5file(filename):
    md5 = hashlib.md5()
    with open(filename, 'rb') as f:
         for chunk in iter(lambda: f.read(8192), ''):
             md5.update(chunk)
    return md5.digest()
