keep floor(i) unchanged if i is imaginary symbol
Changed __add__ to return the correct phase for the addition of two TWave objects
change warning flag to warn in line with code
Adds line wrapping to Fortran codegen call signatures.

Fortran has a maximum line length of 132 characters. The fcode printer handles
this for the expressions itself, but the call signature failed to wrap if the
number or length of arguments is too large. This fix should deal with most
normal cases.

Fixes issue #7934.
Added field numbers in .format call for Python 2.6 compatibility.
test non-linear equations in _solve_system
cache autowrap
add pi/2 awareness to piecewise of Ray when giving arbitrary angle

Fix the MathJax CDN

The old CDN gives 404. We also need to go in the docs repo and retroactively
fix all built docs there.

Fixes #7983.
