Carl -- what I did at dev1

1. Fixed a lot of coercion-branch doctests.

2. Discussed changes to Cython for fast numpy array access (and some other language/compiler changes).

3. Discussed changes to fast_float: support more data types than only C doubles; evaluate DAGs with shared subexpressions; support conditionals; and possibly use a JIT for a further speedup (probably at least 5x on "sufficiently complicated" examples).

4. Demonstrated sage_input and posted a preliminary version on TRAC (http://sagetrac.org/sage_trac/ticket/3485)

Example:

sage: sage_input((polygen(GF(3))+1)^4)

R.<x> = GF(3)[]
x^4 + x^3 + x + 1
