Detailed Description
IncrementalIntegrator is an abstract class. A subclass of it is used when performing a static or transient analysis using an incremental displacement approach. Subclasses of IncrementalIntegrators provide methods informing the FE\_Element and DOF\_Group objects how to build the tangent and residual matrices and vectors. They also provide the method for updating the response quantities at the DOFs with appropriate values; these values being some function of the solution to the linear system of equations. \

To inform the DOF\_Group how to build its tangent matrix for addition to the system of equations. The subclasses must provide the implementation of this method. This is required in transient analysis as th Node objects have mass. THIS MAY CHANGE.
Reimplemented from Integrator.
Reimplemented in HHT, Newmark, and StaticIntegrator. |

Invoked to form the unbalance. The method fist zeros out the 
vector of the LinearSOE object and then invokes formElementResidual() and formNodalUnbalance() on itself.
