Merged marklogic-junit library into marklogic-unit-test (#66)

Bumped version to 0.13.develop. Once this is ready for 0.13.0 or 1.0.0, will need to update the references to 0.13.develop. 

Also made a fix in marklogic-unit-test-client/build.gradle so that createHttpCredentials isn't executed when any task is run, but only when it's run. 

See the README file in the marklogic-junit directory for more information.

+## Easy JUnit 5 testing with MarkLogic
+
+Want to write JUnit 5 tests that verify the behavior of endpoints in [MarkLogic](https://www.marklogic.com/), 
+including applications using the [Data Hub Framework](https://marklogic.github.io/marklogic-data-hub/)? 
+This library makes that as simple as possible by providing the following support:
+
+1. Connect to MarkLogic with the [MarkLogic Java Client](https://developer.marklogic.com/products/java) by reusing
+configuration you've already defined in your project
+1. Clear your test database before a test run so it always runs in a known state
+1. Easily read and make assertions on JSON and XML documents, including support for XPath-based assertions
+1. Easily integrate [marklogic-unit-test](https://github.com/marklogic-community/marklogic-unit-test) tests into a JUnit test suite
+
+Below is a simple example of a JUnit test that writes a couple documents, runs a search on them, and then reads them 
+back and verifies the contents of each document:
+
+```
+public class SearchTest extends AbstractSpringMarkLogicTest {
+
+	@Test
+	public void twoDocuments() {
+		getDatabaseClient().newXMLDocumentManager().write("/test/1.xml", new StringHandle("<message>Hello world</message>"));
+		getDatabaseClient().newJSONDocumentManager().write("/test/2.json", new StringHandle("{\"message\":\"Hello world\"}"));
+
+		QueryManager queryManager = getDatabaseClient().newQueryManager();
+		SearchHandle searchHandle = queryManager.search(queryManager.newStringDefinition(), new SearchHandle());
+		assertEquals(2, searchHandle.getTotalResults());
+
+		XmlNode xml = readXmlDocument("/test/1.xml");
+		xml.assertElementValue("/message", "Hello world");
+
+		JsonNode json = readJsonDocument("/test/2.json");
+		assertEquals("Hello world", json.get("message").asText());
+	}
+}
+```
+
+## Getting started on an ml-gradle project
+
+If you'd like to use marklogic-junit on a regular ml-gradle project (not a DHF project), then 
+start with the ml-gradle example project to see a working example with instructions on how to get started. 
+
+## Getting started on a Data Hub Framework project
+
+If you're working on a Data Hub Framework (DHF) project and you're like to start writing JUnit tests to verify your application 
+features, then check out the DHF example project to see a working example with instructions on how to get started.

+This project shows an example of using both marklogic-junit and marklogic-unit-test within a 
+Data Hub Framework version 4 project. 
+
+To try this out locally, first initialize the DHF project:
+
+    ./gradlew hubInit
+    
+Then add the following lines to gradle.properties:
+
+```
+mlModulePaths=src/main/ml-modules,src/test/ml-modules
+mlTestDbName=data-hub-TEST
+mlTestDbFilename=final-database.json
+mlTestServerFilename=final-server.json
+mlTestServerName=data-hub-TEST
+mlTestPort=8015
+mlTestUsername=someuser
+mlTestPassword=someuser's password
+```
+
+You can now deploy both the normal DHF application and the test resources defined in build.gradle via:
+
+    ./gradlew mlDeploy testDeploy
+
+There are two marklogic-unit-test test modules under ./src/main/ml-modules/root/test. You can run these 
+via Gradle:
+
+    ./gradlew test
+
+And Gradle should report "BUILD SUCCESSFUL" as none of the tests should fail.
+
+Or import this project into your favorite IDE and execute "RunDataHubUnitTestsTest". Each test module 
+will be executed as a separate JUnit test.
