Try fix issue with only on class name

Try fix  logic based on class name, and change it on nib or reuseIdentifier. Now i can create some classes for other reuseidentifiers. Trouble described [this issue](https://github.com/Raizlabs/RZCellSizeManager/issues/27)
Oops, didn't realize `overideWidth` wasn't your property. No need to change it.
