The email regexp was improved to be case-insensitive.
Old is_valid_email() function was removed.
is_valid_email2() function was renamed to is_valid_email() in order to
be more user-friendly.
Code readability was improved.
Added a new function within the ooxml_util_pkg specifications that will return a collection of the worksheet records that include the name of the worksheet, the sheet ID of the worksheet, and the relationship ID for the worksheet. This will allow for the ability to look-up worksheets and parse them without needing to know what the worksheet's name is in advance.
