ExcelBuilder - A Groovy Builder for Excel Spreadsheets

This provides a builder-style interface for creating Excel (2007+ format) spreadsheets using the Apache POI library.

The documentation is currently ... sparse. But the unit tests provide many examples of how to use it. To give you an idea of the main features here is a quick example:

def builder = new ExcelBuilder()
builder {
	font('title') {
		bold = true
		color = IndexedColors.RED.index
	}
	style('centred') {
		alignment = CellStyle.ALIGN_CENTER
	}
	style('uk-date') {
		dataFormatString = 'dd/mm/yyyy'
	}
	sheet {
		row([1, 2, 'Hello'], style: ['centred', 'title'])
		row([5, 6, 7], style: 'centred')
		row(['Today', new Date()]) {
			cell(column: 1, style: 'uk-date', width: 20)
		}
	}
}
builder.workbook.write(new FileOutputStream(new File('test.xlsx')))

This produces a workbook with a sheet that looks something like this:

There are more features to come, but it's fully functional right now.
