/*
Account number composition:
EXAMPLE:
KCSB-9284-0JKI94358732
EXPLANATION:
The composition of the above number is mostly not random. The composition is 'C' = LETTER, and the first 4 represent the 4-letter combination
of the financial establishment (think of the stock market NASDAQ). The first 4 '#' (# = Number) digits represent the ROUTING number of the bank.
The next '#' (in its own brackets) represents ACCOUNT TYPE. This means the mod supports up to 9 configurations; some examples would be CHECKING
or SAVINGS. The next three '#' (in their own brackets too) will be the first three letters of the username of the account holder inside an ASCII
table. If the letter is not UTF 8 compatible - then the default will be '0'. The LAST eight '#' (not in brackets) are randomly generated via Java.
* Please note that the brackets in this example are only for demonstration of separating numbers from each other. They do not show up at all in generation.
CCCC-####-[#][###]########
* Additional note - enums are not implicitly integers under the hood like C++; so, a financial establishment could pass in ANY 0-9 digit for "account type" and
each establishment is allowed to treat that however they want. In one banks case it make checking accounts 3; but in anothers it's 4. This is a general programming
note for now. It is probably best to keep this consistent in your server/mod so tellers can understand them universally.
