This command is used to construct a KrylovNewton algorithm object which is uses a Krylov subspace accelerator to accelerate the convergence of the modified newton method. The command is of the following form:
| algorithm Newton <-iterate $tangIter> <-increment $tangIncr> <-maxDim $maxDim> |
| $tangIter | tangent to iterate on, options are current, initial, noTangent. default is current. |
| $tangIncr | tangent to increment on, options are current, initial, noTangent. default is current |
| $maxDim | max number of vectors stored. |
