640af2b413 Remove abstract operators from BigNumber, rename divide methods in BigDecimal 
It turned out that there was no value in having a generic interface for operations, when every concrete class could really only accept instances of itself, and more importantly, would only return instances of itself. This was also a problem for division, that cannot be handled in the same way for BigInteger, BigDecimal and BigRational.

Methods changed in BigDecimal:

- dividedBy() is now exactlyDividedBy(), and always calculates the scale automatically
- dividedToScale() is now dividedBy(), and does not not make any assumption on the scale any more

a32db93675 Move rounding code back to Calculator 
It was a mistake to move it to BigDecimal, this is where it belongs.

271b619453 Rename BigDecimal::dividedAndRemainder() to quotientAndRemainder() 
This is consistent with the naming of the BigInteger method.

38a6b8c342 Add BigNumber::toInteger() and toFloat() methods 
These methods are implemented by BigInteger, BigDecimal and BigRational.

- toInteger() returns an exact value or throws an exception
- toFloat() returns an approximate value

45e3c3a463 Remove get prefix in method names 
This improves overall consistency of method names in the project.
For example, it does not make sense to get the reciprocal of a BigRational using reciprocal(), but get its numerator using getNumerator().

List of renamed methods:

- BigNumber::getSign() => sign()
- BigDecimal::getUnscaledValue() => unscaledValue()
- BigDecimal::getScale() => scale()
- BigDecimal::getIntegral() => integral()
- BigDecimal::getFraction() => fraction()
- BigRational::getNumerator() => numerator()
- BigRational::getDenominator() => denominator()

97c7c45c51 All BigNumber subclasses now have zero(), one() and ten() factory methods
