Do the flipping trick correctly. Now the entries of a square differentiation matrix are symmetric about the anti-diagonal with an opposite sign.
1. Forcing symmetry for barycentric weights of the first kind points. 2. Forcing symmetry for all square differentiation matrices.
A careless mistake.
Adding tests for exact symmetry of square differentiation matrices.
chebfun.values now returns a vector instead of a cell array. Update chebop2 display method.
Allow operations between CHEBTECH and FOURTECH.
1. Creation of two classes PERIODICTECH and NONPERIODICTECH between SMOOTHFUN and FOURTECH/CHEBTECH. PERIODICTECH is an abstract class with parent SMOOTHFUN and child FOURTECH. NONPERIODICTECH is an abstract class with parent SMOOTHFUN and child CHEBTECH. These two classes have a method ISPERIODIC that returns always 1 for PERIODICTECH and 0 for NONPERIODICTECH.
2. Modifications of +,-,*,/ in CHEBFUN.
1. Adjust the domains.
2. Add tests.

Upping a tolerance before merging in fix-barydiffmat
Resolving merge conflicts
Merge branch 'fix-barydiffmat' into development
1. Rename isperiodic -> isPeriodicTech.
2. Add a isPeriodicTech for SINGFUNs.
3. Modify tolerances in the tests.
Implement isPeriodicTech at the fun level.
Forgot to delete a few commented lines.
