/**
* HSSFDataFormatter contains methods for formatting the value stored in an
* HSSFCell. This can be useful for reports and GUI presentations when you
* need to display data exactly as it appears in Excel. Supported formats
* include currency, SSN, percentages, decimals, dates, phone numbers, zip
* codes, etc.
*
* Internally, formats will be implemented using subclasses of {@link Format}
* such as {@link DecimalFormat} and {@link SimpleDateFormat}. Therefore the
* formats used by this class must obey the same pattern rules as these Format
* subclasses. This means that only legal number pattern characters ("0", "#",
* ".", "," etc.) may appear in number formats. Other characters can be
* inserted before or after the number pattern to form a
* prefix or suffix.
*
*
* For example the Excel pattern "$#,##0.00 "USD"_);($#,##0.00 "USD")"
* will be correctly formatted as "$1,000.00 USD" or "($1,000.00 USD)".
* However the pattern "00-00-00" is incorrectly formatted by
* DecimalFormat as "000000--". For Excel formats that are not compatible with
* DecimalFormat, you can provide your own custom {@link Format} implementation
* via HSSFDataFormatter.addFormat(String,Format). The following
* custom formats are already provided by this class:
*
*
*
- SSN "000-00-0000"
* - Phone Number "(###) ###-####"
* - Zip plus 4 "00000-0000"
*
*
* If the Excel format pattern cannot be parsed successfully, then a default
* format will be used. The default number format will mimic the Excel General
* format: "#" for whole numbers and "#.##########" for decimal numbers. You
* can override the default format pattern with
* HSSFDataFormatter.setDefaultNumberFormat(Format). Note: the
* default format will only be used when a Format cannot be created from the
* cell's data format string.
