Refactor NumberConversionUtil and toString() of CookieList & XML Classes.

[adityap27]

Hello @stleary,

I have made 3 refactorings.

1. Renamed Variable boolean b in toString() method of CookieList Class.
boolean isEndOfPair is more meaningful as compared to just boolean b.

2. Introduced indentationSuffix variable in toString() method of XML Class.
There are multiple long expressions which are using (indentFactor > 0) ? "\n" : "" sub-expression. indentationSuffix is introduced to replace this sub-expression to improve readability and reduce duplication.

3. Added method isNumericChar(...) in NumberConversionUtil Class.
There are some digit-related conditions which may look complex to some developers due to multiple conditional operators.
Eg: if ((initial >= '0' && initial <= '9') || initial == '-' )
and if(at1 == '0' && at2 >= '0' && at2 <= '9')

The sub-condition c >= '0' && c <= '9' is moved to a method isNumericChar(...) to reduce the complexity of these conditions and better readability.

Notes:
All the unit tests are passing successfully.

This code is compatible with Java 6.
