MAIN SCREEN TURN ON. HOW ARE YOU GENTLEMEN!! WHAT HAPPEN? YOU ARE ON THE WAY TO NEW FEATURES: * Ctors of class numeric are not explicit any more. All built-in callers for pseudofunctions are now templated and default to ex arguments which relaxes the need for explicit ctors. * New functions/methods: - find() - remove_first(), remove_last(), sort() and unique() for lists - symmetrize_cyclic() - decomp_rational() * Instead of just totally symmetric or antisymmetric, complex symmetries can now be defined for indexed objects. Symmetries are described by a tree of "symmetry" objects that is constructed with the sy_none(), sy_symm(), sy_anti() and sy_cycl() functions. The symmetry of a function with respect to its arguments can also be defined (this is currently only used for the Beta function). * Generalized map() to take a function object instead of a function pointer. This allows passing an arbitrary number of additional state to the function being called. * color_trace(), dirac_trace(), diff(), expand(), evalf() and normal() work better with container classes, e.g. using color_trace() on a relation will take the trace on both sides, using diff() on a matrix differentiates every element etc. * diff() works properly with non-commutative products and indexed objects. * New option flag "expand_function_args" for expand(). * Supplement some (now deprecated) macros by inlined template functions: - is_of_type(foo, type) -> is_a<type>(foo) - is_ex_of_type(foo, type) -> is_a<type>(foo) - is_exaclty_of_type(foo, type) -> is_exaclty_a<type>(foo) - is_ex_exaclty_of_type(foo, type) -> is_exaclty_a<type>(foo) - ex_to_foobar(baz) -> ex_to<foobar>(baz) * rem(c, p[x], x) (c: numeric, p[x]: polynomial) erroneously returned p[x] instead of c. * Small bugfixes in pattern matching. * Updated libtool to version 1.4.
