reference tests as examples

Remove samples and reference the tests as examples instead.

We don't need these samples for two reasons:
1. It is already duplicated in either JJB tests or documentation.
2. We don't test these samples so they may become outdated (some already have).

 # Jenkins Job Builder Examples #
 
-These examples demonstrate the use of particular features of Jenkins
-Job Builder that can be used as starting points for new projects.
+Jenkins Job Builder includes many tests to demonstrate the use of Jenkins
+Job Builder.  All of the tests are in the 'tests' folder.  It can be used
+as a starting point for new projects.  The tests also serve as JJB docs.
 
-These examples are also used in the test framework - if you add a new
-example here, please ensure that it can be processed by Jenkins Job
-Builder.
+Please look in the tests folder for examples of how to define yaml files
+for use with JJB.  Most of the test examples are snippets of yaml, for a
+more complete example look at the tests in the 'tests/yamlparser' folder.

-# Sample YAML representation of a flexible pipeline for use with the
-# Jenkins Build Pipeline Plugin
-# (https://wiki.jenkins-ci.org/display/JENKINS/Build+Pipeline+Plugin)
-# The pipeline is defined at the project level, using job-specific variable
-# substitution to specify the next job in the pipeline ('pipeline-next') 
-# for each job.
-#
-# This example defines the skeleton of two deployment pipelines: one for
-# a 'base_os' subsystem to three chef servers, and the second to
-# a 'database' subsystem to two chef servers.
-# 
-# The pipeline uses an automatically-executed job in '{subsys}-prepare'
-# (using the Parameterized Trigger Plugin - 
-# https://wiki.jenkins-ci.org/display/JENKINS/Parameterized+Trigger+Plugin),
-# and manually-triggered jobs using the Pipeline publisher (e.g.
-# '{subsys}-initialise').
-#
-# Note how each project defines a different pipeline, with a different
-# length, but re-uses the same job templates.
