[stringtemplate-interest] ST4: simple write to file method.

[Terence Parr]

I'm adding a few options. will this work for you?

Ter
	public int write(File outputFile, STErrorListener listener)
		throws IOException
	{
		return write(outputFile, listener, Locale.getDefault(), STWriter.NO_WRAP);
	}

	public int write(File outputFile, STErrorListener listener, int lineWidth)
		throws IOException
	{
		return write(outputFile, listener, Locale.getDefault(), lineWidth);
	}

	public int write(File outputFile,
					 STErrorListener listener,
					 Locale locale,
					 int lineWidth)
		throws IOException
	{
		Writer bw = null;
		try {
			FileOutputStream fos = new FileOutputStream(outputFile);
			OutputStreamWriter osw = new OutputStreamWriter(fos);
			bw = new BufferedWriter(osw);
			AutoIndentWriter w = new AutoIndentWriter(bw);
			w.setLineWidth(lineWidth);
			int n = write(w, locale, listener);
			bw.close();
			bw = null;
			return n;
		}
		finally {
			if (bw != null) bw.close();
		}
	}
