/**
* This is the Runtime system for Velocity. It is the
* single access point for all functionality in Velocity.
* It adheres to the mediator pattern and is the only
* structure that developers need to be familiar with
* in order to get Velocity to perform.
*
* The Runtime will also cooperate with external
* systems like Turbine. Runtime properties can
* set and then the Runtime is initialized.
*
* Turbine for example knows where the templates
* are to be loaded from, and where the velocity
* log file should be placed.
*
* So in the case of Velocity cooperating with Turbine
* the code might look something like the following:
*
* <pre>
* RuntimeSingleton.setProperty(RuntimeConstants.FILE_RESOURCE_LOADER_PATH, templatePath);
* RuntimeSingleton.setProperty(RuntimeConstants.RUNTIME_LOG, pathToVelocityLog);
* RuntimeSingleton.init();
* </pre>
*
* <pre>
* -----------------------------------------------------------------------
* N O T E S O N R U N T I M E I N I T I A L I Z A T I O N
* -----------------------------------------------------------------------
* RuntimeSingleton.init()
*
* If Runtime.init() is called by itself the Runtime will
* initialize with a set of default values.
* -----------------------------------------------------------------------
* RuntimeSingleton.init(String/Properties)
*
* In this case the default velocity properties are layed down
* first to provide a solid base, then any properties provided
* in the given properties object will override the corresponding
* default property.
* -----------------------------------------------------------------------
