/**
 * Class that represents a function that is integrated with Api Gateway.
 * The reason for creating this wrapper class is so that a plain apiMethodName
 * can be associated with the Function, that does not include the hashes created by the CDK
 * when using the regular function name as part of the logical identifier.
 * Without this, when creating dashboards, we will run into the error of not being able to name the dashboards
 * using the as-of-yet unresolved tokens representing the function names
 *
 * See the following for more details,
 *
 * https://docs.aws.amazon.com/cdk/latest/guide/identifiers.html
