Classes for generic manipulation with mathematic constructs:
* numbers
* complex numbers
* fractions
* matrixes
* geometry
* ...
For example, to create a generic sum or coprime function:
```
public static T sum(Collection elements, Arithmetics arit) {
T res = arit.zero();
for(T t : elements)
res = arit.add(res, t);
return res;
}
public static boolean coprime(T a, T b, IntegralArithmetics arit) {
return arit.gcd(a, b).equals(arit.one());
}
```
And calling it:
```
ArrayList integerList;
ArrayList doubleList;
sum(integerList, IntegerArithmetics.getInstance());
sum(doubleList, DoubleExactArithmetics.getInstance());
coprime(55, 128, IntegerArithmetics.getInstance());
coprime(new BigInteger("55"), new BigInteger("128"), BigIntegerArithmetics.getInstance());
```
