Hide all value objects and abstract value object functionality behind static factory methods in a new Values class

Client code should not have access to IntegerValue, StringValue, LongValue, ... These values should be made protected and moved to the package org.openfast.value. A new class org.openfast.value.Values should be used to construct these objects.

public class Values {
private Values() {}
public static integer(String value)

{...}
public static integer(int value) {...}

public static integer(long value)

{...}
public static ulong(long value) {...}

public static string(String value)

{...}
public static byteVector(String hexString) {...}

public static byteVector(byte[] value)

{...}
public static decimal(String value) {...}

public static decimal(double value, int precision)

{...}
public static decimal(BigDecimal value) {...}

}
