Oops. Remove the #q reader functions from here.

They've been moved to qd-reader.lisp.

commit 3d37e3b9346092b58e820723ae20f114dc912d44 Author: Raymond Toy toy.raymond@gmail.com Date: Tue Mar 8 09:01:06 2011 -0500

Move #Q reader functions to new file qd-reader.lisp.

qd-reader.lisp: o New file containing #Q reader functions. o Create a new readtable containing our reader functions so we don't destructively modify the default *readtable*.

oct.asd: o Add qd-reader.lisp.

qd-complex.lisp: qd-elliptic.lisp: qd-format.lisp: o Set the *readtable* to *oct-readtable* before compiling these files.
