Initial import to libchebfun repo.
added option "--add-missing" to the automake call and made the script executable.
swapped test_[pedro|nick] to [pedro|nick]_test.
removed dropbox-folder that somehow snuck-in to the trunk.
added call to autoheader to build config.h.in.
automatically generated by aclocal -- not needed.
generated automatically by automake, not needed here.
automatically generated by automake, not needed here.
generated automatically by autoheader in autogen.sh, not needed here.
automatically generated by automake in autogen.sh, not needed here.
removed ax_blas and ax_lapack and replaced them with AC_CHECK_[LIB|HEADER] since the ax_[blas|lapack] somehow require an F77 compiler...
since we're not using ax_blas or ax_lapack, no need for this.
added ax_prog_doxygen.m4 since can't assume that all users will have this...
Initial approximations to restrict, simplify, and roots.
So far roots only constructs the colleague matrix and doesn't
support recursion. Simplify doesn't support a tolerance, 
only what is defined in chebopts.eps. Restrict should be
OK though!

Also added _fun_alloc, which simply allocates memory for
a fun of size N (i.e. with no zeroing of rows, or assigning
of Chebyshev points). This should be used in fun_create_vec?
Added fun_copy to copy a fun. Fixed restrict and added recursion aspect of roots_unit. Now need to link to LAPACK to solve the (upper-hessenberg?) eigenvalue problem.
This and that...
Added roots, max, min, and norm_inf.
some minor fixes and changed the interface of fun_roots_unit -- something still buggy though.
Fix in fun_roots_unit regarding WTF error message.
fixed bug in fun_roots_unit.
