/**
* The VersionInfo class contains strings that describe the implementation
* and specification version of the javafx pacakges. These strings
* are made available as properties obtained from the System Properties class.
*
*
* This class serves 3 purposes:
*
* 1. It creates the JavaFX version properties to be added into the Java
* System Properties at the loading of the JavaFX Toolkit. The JavaFX properties
* are javafx.version and javafx.runtime.version. Their formats follow the
* specification of java.version and java.runtime.version respectively.
* See http://openjdk.java.net/jeps/223 for details.
*
* For example, an early access build of JavaFX 9 build 76 will contain
* the following properties:
*
* javafx.version = 9-ea
* javafx.runtime.version = 9-ea+76
*
* An fcs build of JavaFX 9 build 135 will contain the following properties:
*
* javafx.version = 9
* javafx.runtime.version = 9+135
*
* 2. It provides methods to access Hudson build information and timestamp.
* These methods can be used to uniquely identify a particular build
* for internal test and deployment:
*
* The method getHudsonJobName() will returns the name of the hudson job.
* For example, a master build will have the name as "presidio", and a
* graphics-scrum will have the name as "presidio-graphics" and so for.
* An empty string is returned if the build isn't build on Hudson, such as a
* local build on a developer machine.
*
* The method getHudsonBuildNumber() will returns the number of the hudson job
* on a particular build scrum. The job number is sequentially incremented for
* each build job.
* For example, a master build job number of 25 was built before master job
* number 26.
* A string of zeros is returned if the build isn't build on Hudson, such as a
* local build on a developer machine.
*
* The method getBuildTimestamp() will returns the timestamp of the build.
*
* 3. To uniquely identify a build that isn't generated on Hudson, such as a
* local build on a developer machine. It substitutes the build number tag of
* the javafx.runtime.version string with the build timestamp.
* For example, a build of JavaFX 9 on a developer machine will look
* something like the following:
*
* javafx.version = 9-internal
* javafx.runtime.version = 9-internal+0-2015-08-10_22-08-04
*
*
* The tags of the form @STRING@ are populated by ant when the project is built
*
* @see System#getProperties
