Declares that a custom BinarySpec type. The following example demonstrates how to register a custom component type using a plugin with a BinaryType annotation.

 import org.gradle.model.*
 import org.gradle.model.collection.*

 interface SampleBinary extends BinarySpec {}
 class DefaultSampleBinary extends BaseBinarySpec implements SampleBinary {}

 apply plugin: MySamplePlugin

 class MySamplePlugin implements Plugin {
     void apply(final Project project) {}

     @RuleSource
     static class ComponentModel {
         @BinaryType
         void defineBinaryType(BinaryTypeBuilder builder) {
             builder.defaultImplementation(DefaultSampleBinary)
         }
     }
 }
