chebcoeffs now returns a column vector with the zeroth order coefficient at the top and highest at the bottom.
test_chebcoeffs now passes.
flipping coefficients for chebpoly construction.
making legcoeffs consistent with chebcoeffs
fixing order of coeffs in cheb2leg and leg2cheb
making sure various tests pass.
all xyzpoly are now fine.
conv now works with the new coefficient ordering.
polynomail cf now works with new coeff ordering.
chebpade now works with new coeffs.
Rational CF now works
ratinerp fixed for new coefficient ordering.
making sure legcoeffs returns a vector of length n+1 as advertised.
Making legcoeffs consistent with chebcoeffs

legcoeffs(f,n) and chebcoeffs(f,n) both return exactly n coefficients
and not n+1.
minor fix to a test.
making chebfun2 compatible with new coefficient ordering at the user level
Merge branch 'development' of https://github.com/chebfun/chebfun into fix-chebcoeffs
first roots test passed!
adjust tolerance for a test.
fixing chebop2 to work with new coefficient ordering.
