/**

* Various utility functions that make working with a cells and rows easier. The various methods

* that deal with style's allow you to create your CellStyles as you need them. When you apply a

* style change to a cell, the code will attempt to see if a style already exists that meets your

* needs. If not, then it will create a new style. This is to prevent creating too many styles.

* there is an upper limit in Excel on the number of styles that can be supported.
