* Internal helper class for CellNumberFormatter
*
* This class represents a single modification to a result string. The way
* this works is complicated, but so is numeric formatting. In general, for
* most formats, we use a DecimalFormat object that will put the string out
* in a known format, usually with all possible leading and trailing zeros.
* We then walk through the result and the original format, and note any
* modifications that need to be made. Finally, we go through and apply
* them all, dealing with overlapping modifications.
