Add support for styling

Added top level methods on the Writer: - addRowWithStyle() - addRowsWithStyle() Added a style builder, to easily create new styles. Each writer can specify its own default style and all styles will automatically inherit from it. For now, the style properties supported are: - bold - italic - underline - strikethrough - font size - font name - wrap text (alignment)
