Class CellHelper
This class provides helper functions when working with cells

getColumnLettersFromColumnIndex($columnIndexZeroBased)   X-Ref
Returns the column letters (base 26) associated to the base 10 column index.
Excel uses A to Z letters for column indexing, where A is the 1st column,
Z is the 26th and AA is the 27th.
The mapping is zero based, so that 0 maps to A, B maps to 1, Z to 25 and AA to 26.

return: string The associated cell index ('A', 'BC', ...)
param: int $columnIndexZeroBased The Excel column index (0, 42, ...)
