com.google.visualization.datasource.datatable.ValueFormatter
Formats a {@link Value}, or parses a string to create a {@link Value}. An instance of this class can be created using the {@link #createFromPattern(ValueType,String,ULocale)} method, and can then use the formatand/or parse.
The class also supplies a set of default patterns per {@link ValueType}. The default patterns can be used for parsing/formatting values when there is no specified pattern. Otherwise, create a class instance by specifying a pattern and locale.
Note: This class is not thread safe since it uses {@code UFormat}. @author Yonatan B.Y.
