This function evaluates the bit strength of a users input.

For example, if a user entered the following:
password

The effective bit size of 'password' is 38-bits.

If the user entered:
Password

The effective bit size of 'password' is 46-bits.

If the user entered:
P@ssw0rd

The effective bit size of 'password' is 52-bits.

The higher the bit size, the stronger the password.
