// Use Expression to filter by cost or by usage. There are two patterns:
//
//    * Simple dimension values - You can set the dimension name and values
//    for the filters that you plan to use. For example, you can filter for
//    INSTANCE_TYPE==m4.xlarge OR INSTANCE_TYPE==c4.large. The Expression for
//    that looks like this:
//
// { "Dimensions": { "Key": "INSTANCE_TYPE", "Values": [ "m4.xlarge", “c4.large”
//    ] } }
//
// The list of dimension values are OR'd together to retrieve cost or usage
//    data. You can create Expression and DimensionValues objects using either
//    with* methods or set* methods in multiple lines.
//
//    * Compound dimension values with logical operations - You can use multiple
//    Expression types and the logical operators AND/OR/NOT to create a list
//    of one or more Expression objects. This allows you to filter on more advanced
//    options. For example, you can filter on ((INSTANCE_TYPE == m4.large OR
//    INSTANCE_TYPE == m3.large) OR (TAG.Type == Type1)) AND (USAGE_TYPE !=
//    DataTransfer). The Expression for that looks like this:
//
// { "And": [ {"Or": [ {"Dimensions": { "Key": "INSTANCE_TYPE", "Values": [
//    "m4.x.large", "c4.large" ] }}, {"Tag": { "Key": "TagName", "Values": ["Value1"]
//    } } ]}, {"Not": {"dimensions": { "Key": "USAGE_TYPE", "Values": ["DataTransfer"]
//    }}} ] }
//
// Because each Expression can have only one operator, the service returns an
//    error if more than one is specified. The following example shows an Expression
//    object that creates an error.
