Enum type column

This module allows to set enum type on a column from a table which is defined in custom module.

Sometimes we want to restrict user to use only some limited values in the form components. This module tries to provide a solution which enables user to set enum type on certain columns. It has also revert feature in case user wants to revert enum type from the column.

Some features:

1. Sets enum type on a column on a custom module table
2. Maintains history of operations performed on a column. ie. - Changing and reverting structure of a column
3. User has also the feature to revert enum type from a column of a table.

Note: Consider only modules which are kept in modules/custom directory.
