* 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:
*
* <blockquote><code><pre>
* ri.setProperty(Runtime.FILE_RESOURCE_LOADER_PATH, templatePath);
* ri.setProperty(Runtime.RUNTIME_LOG, pathToVelocityLog);
* ri.init();
* </pre></code></blockquote>

* with a set of default values.

* In this case the default velocity properties are layed down
