Need to (re)initialize dYdY0 for multiple integrate with FirstOrderIntegratorWithJacobians
------------------------------------------------------------------------------------------
Key: MATH-380
URL: https://issues.apache.org/jira/browse/MATH-380
Project: Commons Math
Issue Type: Bug
Affects Versions: 2.1
Reporter: Pascal Parraud
Priority: Minor
There is a lack in the method integrate of FirstOrderIntegratorWithJacobians. The jacobian
DYDY0 can't be initialized by the user, unlike DFDP with DF0DP.
So, for several successive integrations, the matrix is reinitialized to identity and that
is not what we might want.
