◆ deriveBranch()

CEvaluationNode * CDerive::deriveBranch	(	const CEvaluationNode *	node,
		const CDataObject *	pObject
	)

create a derivative of a mathematical expression with root at *node with respect to the variable *pObject. in env we pass the vector of trees that will be substituted for variable nodes The treatment of object nodes in env[] is specific:

It is assumed that the value of all the objects is updated before the derivative will be evaluated (the evaluation of objects is not expanded)
However, the derivation of objects is expanded, for entities with assignments, concentrations, dependent species, reactions.

Parameters

node
pObject	the variable to derive
env	vector of trees to be substituted for variable nodes
pTree,the	tree to differentiate
simplify	if true the expression will be simplified
