The public methods expression() systematically returns (a const reference to) an expression adapter derived from template Expression_Adapter (including Expression_Hide_Inhomo and Expression_Hide_Last). These adapters provide a *read-only* interface enabling most (but not all) of the operations that can be performed on a Linear_Expression. Added four templatic constructors to Linear_Expression accepting any such adapter. Removed a dozen specific constructors that were tailored to the four classes Constraint, Generator, Congruence and Grid_Generator. As a consequence previous code such as Linear_Expression expr(gen); will no longer compile and should be replaced by Linear_Expression expr(gen.expression()); The systematic use of the new adapters, besides removing some indirections, also decreases the memory overhead of classes Constraint, Generator and Grid_Generator, as we no longer need members `wrapped_expr' and `semi_wrapped_expr'. While at it, corrected a few latent bugs in adapter Expression_Hide_Inhomo (these could not manifest as real failures because currently the Hide_Inhomo adapter is always re-wrapped using the Expression_Hide_Last adapter).
