Alter Manager is a service that is responsible for changing the formula expressions (especially cell coordinates)
based on specific alter operation applied into the table.
For example, when a user adds a new row the algorithm that moves all the cells below the added row down by one row
should be triggered (eq: cell A5 become A6 etc).
All alter operations are defined in the "alterOperation/" directory.
