GitHub repo for proposed new functions to Flint

[American Citizen]

Please see https://github.com/reader3/flint_code

The proposed additions to flint are:

   int acb_norm(arb_t mod, const acb_t x, const slong prec)

   int acb_set_str(acb_t res, const char * inp, slong prec)

   acb_set_ui_ui(acb_t z, ulong x, ulong y) [inside acb.h]

   long autoset_bin_prec(const char* inp) [utility function]

p.s. I probably will add the documentation for each to the repo.
