/*TO DO
* Go through all previous purchases and
* erase them from the user's List of Answers:
* Use String.Replace to finally replace the Purchase_ clause
* Then split the answer string based on the
* replacing string (which must also be a single character)
* "*" for example.
* Save each component of the string so that it can be
* reconstructed to the original answer string for that user
* The frist string in the array will be al answers
* before the recent purcahse, the following strings will be
* all purchases after that one.
* It is important to note that all of the strings other than the first
* will be ones that started with purchase meaning they will have the
* answer that has just been purchased plus all answers already payed for
* after that purcahase up until the next new purchase.
* Each of these substrings should be split on the ';' character to isolate
* the file name of the solution just purchased.
*
* Or the easy way is to replace "Purchase_" with "".
* //*/
//thisUser.Answers += "" + "Purchase_" + filename + ";";//Purchase indicates that the item is not yet payed for.
