Adding PayPal Express Checkout Support

Add the following component scan in your applicationContext-servlet.xml in your site module

    <context:component-scan base-package="org.broadleafcommerce.vendor.paypal"/>

Add the PayPal Express component scan in your applicationContext.xml of your core module
Declare the bean org.broadleafcommerce.vendor.paypal.service.payment.PayPalExpressPaymentGatewayType so that Spring can initalize the Broadleaf Enumeration for both Site and Admin
Inject the PayPalExpressCheckoutLinkProcessor into the Broadleaf Thymeleaf Dialect Processors blDialectProcessors in your applicationContext.xml of your core module
Inject the blPayPalExpressConfigurationService bean into the blPaymentGatewayConfigurationServices list in your applicationContext.xml of your core module

Example:

    <!-- PayPal Express Checkout -->
    <context:component-scan base-package="org.broadleafcommerce.payment.service.gateway"/>
    <context:component-scan base-package="org.broadleafcommerce.vendor.paypal"/>
    <bean class="org.broadleafcommerce.vendor.paypal.service.payment.PayPalExpressPaymentGatewayType"/>

    <bean id="blPayPalExpressCheckoutLinkProcessor" class="org.broadleafcommerce.vendor.paypal.web.processor.PayPalExpressCheckoutLinkProcessor"/>
    <bean id="myCompanyPaymentProcessors" class="org.springframework.beans.factory.config.SetFactoryBean">
        <property name="sourceSet">
            <set>
                <ref bean="blPayPalExpressCheckoutLinkProcessor"/>
            </set>
        </property>
    </bean>
    <bean class="org.broadleafcommerce.common.extensibility.context.merge.LateStageMergeBeanPostProcessor">
        <property name="collectionRef" value="myCompanyPaymentProcessors"/>
        <property name="targetRef" value="blDialectProcessors"/>
    </bean>

    <bean id="mySampleConfigurationServices" class="org.springframework.beans.factory.config.ListFactoryBean">
        <property name="sourceList">
            <list>
                <ref bean="blPayPalExpressConfigurationService"/>
            </list>
        </property>
    </bean>
    <bean class="org.broadleafcommerce.common.extensibility.context.merge.LateStageMergeBeanPostProcessor">
        <property name="collectionRef" value="mySampleConfigurationServices"/>
        <property name="targetRef" value="blPaymentGatewayConfigurationServices"/>
    </bean>
