Bug Description
Many operator related methods are missing in org.jquantlib.
Example:
C++:
inline Period operator-(const Period& p) {
return Period(
}
This function simply creates a new instances using passed Period.
I don't see any equivalent method in Java. However, there is a minus() method but it uses instances variables.
public Period minus() {
return new Period(
}
Note: many operator related methods in Period are required to implement Schedule.java

Ideally, we should mimic QuantLib/C++ API as close as possible.
Below you can see an skeleton produced by our Python script:
