/**
* A Groovy-based reader for Spring bean definitions: like a Groovy builder, but more of a DSL for

*
* <p>This bean definition reader also understands XML bean definition files, allowing for seamless
* mixing and matching with Groovy bean definition files.
*
* <p>Typically applied to a {@link
* org.springframework.beans.factory.support.DefaultListableBeanFactory} or a {@link
* org.springframework.context.support.GenericApplicationContext}, but can be used against any
* {@link BeanDefinitionRegistry} implementation.
*
* <h3>Example Syntax</h3>
*
* <pre class="code">
* import org.hibernate.SessionFactory
* import org.apache.commons.dbcp.BasicDataSource
*
* def reader = new GroovyBeanDefinitionReader(myApplicationContext)
* reader.beans {
* dataSource(BasicDataSource) { // <--- invokeMethod
* driverClassName = "org.hsqldb.jdbcDriver"
* url = "jdbc:hsqldb:mem:grailsDB"

* }
* myService(MyService) {
* nestedBean = { AnotherBean bean -> // <-- setProperty with closure for nested bean
* dataSource = dataSource
* }
* }
* }</pre>
*
* <p>You can also load resources containing beans defined in a Groovy script using either the
* {@link #loadBeanDefinitions(Resource...)} or {@link #loadBeanDefinitions(String...)} method, with
* a script looking similar to the following.
*
* <pre class="code">
