 * Create the Composite Studio Enable VCS property file.  The property file name is of the format <composite_user>.<domain>.<composite_server_host>.properties.
 * @param vcsIncludeResourceSecurity - the value is either "true" or "false"
 * @param vcsWorkspacePathOverride - this is a way of overriding the vcs workspace path.  The vcsWorkspacePath is derived from the studio.properties file properties:
 *                                   VCS_WORKSPACE_DIR+"/"+VCS_PROJECT_ROOT.  It will use the substitute drive by default.
 * @param vcsScriptBinFolderOverride - this is the bin folder name only for PDTool Studio.  Since PDTool Studio can now support multiple hosts via multiple /bin folders,
 *                             it is optional to pass in the /bin folder location.  e.g. bin_host1, bin_host2.  The default will be bin if the input is null or blank.                                 
 * @param studioPropertyName - the name of the PDTool configuration property file.  The default is studio.properties
 * @param PDToolHomeDir - the directory of the PDToolStudio home directory
 * @param propertyFilePath - this is the full path to the output file.  For windows 7 the location will be in %USERPROFILE%\.compositesw
