/**
 * Defines a class to be used with ODynM.
 *
 * #### Example 1
 * The column names in DynamoDB table for partitionKey and sortKey must be 'pk' and 'sk' respectively.
 * Both types will bve treated as {@link String}. The expressions for partition/sort key must be provided using \@{@link Attribute}
 * decorator.
 * ```ts
 * Item({
 * 	table: 'table'
 * })
 * ```
 *
 * #### Example 2
 * The column names in DynamoDB table for partitionKey and sortKey must be 'pk' and 'sk' respectively.
 * Both types will bve treated as {@link String}.
 *
 * partitionKey will be built from the static part and the substituted value from 'id' member. For example: SOME#1234
 *
 * sortKey is not used.
 *
 * This configuration takes always precedence over \@{@link Attribute} decorator.
 * ```ts
 * Item({
 *		table: 'table',
 *		key: { partitionKey: 'SOME#{{id}}' }
 * })
 * ```
 *
 * #### Example 3
 * The column names in DynamoDB table for partitionKey and sortKey must be 'partition' and 'sort' respectively.
 * The type for partitionKey will default to {@link string}. sortKey will be treated as {@link number}.
 *
 * partitionKey will be built from the static part and the substituted value from 'id' member. For example: SOME#1234
 *
 * sortKey will evaluate to 12345.
 *
 * This configuration takes always precedence over \@{@link Attribute} decorator.
 *
 * ```ts
 * Item({
 * 	table: {
 * 		name: 'table',
 * 		partitionKey: 'partition',
 * 		sortKey: { name: 'sort', type: Number }
 * 	},
 * 	key: { partitionKey: 'SOME#{{id}}', sortKey: '{{id}}' }
 * })
 * ```
 *
 * @param config the configuration of the item
