 * An AWS-Lambda backed custom resource provider, for CDK Construct Library constructs

 * Function. It only supports NodeJS runtimes.
 *
 * **This is not a generic custom resource provider class**. It is specifically
 * intended to be used only by constructs in the AWS CDK Construct Library, and
 * only exists here because of reverse dependency issues (for example, it cannot
 * use `iam.PolicyStatement` objects, since the `iam` library already depends on
 * the CDK `core` library and we cannot have cyclic dependencies).
 *
 * If you are not writing constructs for the AWS Construct Library, you should
 * use the `Provider` class in the `custom-resources` module instead, which has
 * a better API and supports all Lambda runtimes, not just Node.
 *
 * N.B.: When you are writing Custom Resource Providers, there are a number of
 * lifecycle events you have to pay attention to. These are documented in the
 * README of the `custom-resources` module. Be sure to give the documentation
 * in that module a read, regardless of whether you end up using the Provider
 * class in there or this one.
