Need a function that will determine if a passed value meets the following criteria:
if the string is exactly 6 characters long, and all numeric, then I would need the script to fail and report that the string was not in the correct format.
If the string is 7 characters long, then I need to validate that the last 6 characters are all numeric.
If they are, it's assumed that this is a user ID and I need to pass that to another function to determine if that user's profile path and home directory are identical. If they are, return false, if they are not, return true.
If those last 6 characters are not numeric, or if the length of the string differs from 7, then simply return false.
