Updates internal node and element tables.
Since meshes only contain geometric information, the Space class keeps two tables with FEM-related information. The first one, 'ndata', contains DOF numbers and other things for each node. The second table, 'edata', holds element orders and bubble DOF numbers. Both tables are directly indexed by the node and element IDs. The function resize_tables() is called to check whether the tables are large enough to contain all node and element id's, and to reallocate them if not.
Reimplemented from Hermes::Hermes2D::Space< Scalar >.
