Add the local matrix which has been built locally to the main global matrix, using the Eigen library

Remarks
Eigen manages the matrix operations better than CompressedRowSparseMatrix. In terms of performances, it is preferable to go with Eigen.
Parameters
mstatePairThe mapped mechanical state which the local matrix is associated
mappedMatrixThe local matrix
jacobiansThe required mapping jacobians to project from a mechanical state toward the top most mechanical states
mappingGraphThe mapping graph used to know the relationships between mechanical states. In particular, it is used to know where in the global matrix the local matrix must be added.
globalMatrixMatrix in which the local matrix is added.
