Custom MaskCellType to Input Letters or Special Characters

Spread's MaskCellType is used for masking characters to limit user entry wherein we specify which subsets of characters are allowed for each item in the mask. One day, one of our customers came up with this requirement of MaskCellType wherein he wanted to input letter or special character like "#", "^" and "-" in format "XXX-XX-XXX" along with changing lower case input to upper case in MaskedCellType.
