-- | Modify a checked table.
--
--   The first argument is a function that takes the original table name as
--   input and produces a new table name.
--
--   The second argument gives instructions on how to rename each field in the
--   table. Use 'checkedTableModification' to create a value of this type which
--   does no renaming. Each field in the table supplied here has the type
--   'CheckedFieldModification'. Most commonly, the programmer will use the
--   @OverloadedStrings@ instance to provide a new name.
--
-- == Examples
--
--    Rename a table, without renaming any of its fields:
--
-- @
-- modifyCheckedTable (\_ -> "NewTblNm") checkedTableModification
-- @
--
--    Modify a table, renaming the field called @_field1@ in Haskell to
--    "FirstName". Note that below, @"FirstName"@ represents a
--    'CheckedFieldModification' object.
--
-- @
-- modifyCheckedTable id (checkedTableModification { _field1 = "FirstName" })
-- @
