Add Maven pom files.

[highsource]

I'd like to use gcm-rest-client in a Maven project so I've added pom.xml files.

I've used com.google.cloud.messaging as groupId and gcm/gcm-rest-client as artifactIds, hope it works for you. Please feel free to change these values (as well as version).

CLA is signed (highsource).

If using Maven, any thoughts on aligning the directory structure in Maven format? (https://maven.apache.org/guides/introduction/introduction-to-the-standard-directory-layout.html)

No plans currently to change the directory structure, we are using the Maven repository for distribution but it is still an Ant project.

@Mazook It's actually not really necessary.

What would be good, however, is have OSGi metadata. I want to add GCM as a Apache Camel component, Apache Camel expects all the dependencies to be OSGi bundles. I'll file an extra issue for that.

How about at least adding this to the pom?

<build> <sourceDirectory>src/</sourceDirectory> <testSourceDirectory>test</testSourceDirectory> </build>
