HORZCAT or CHEBFUN objects on the same domain.
Adding support for functions with differeing breakpoints.

For now this calls restrict. In future we probably want a quasimatrix.
Very minor style and documentation fixes for horzcat() functions.
Fixing concatenation of array-valued CHEBTECH objects.
Allow for concatenation with empties.
Fix tests for isempty() in fun, chebtech to work with horizontal concatenation.
Don't preallocate pass matrices in tests.

We decided against this in the meeting on 10/23/2013.  It doesn't gain us
anything significant in terms of test performance while creating the
possibility for confusion when people go to modify the tests.
Allowing both 'norecurse' and 'norecursion' in ROOTS().
Merge branch 'development' of ssh://github.com/chebfun/chebfun into development
Adding LOBPTS() and RADAUPTS() for Gauss-Lobatto and Gauss-Radau quadrature.
Iniitial implementation of SCRIBBLE for v5.
Adding REPMAT() and VANDER() methods.

P.S. HAAAAAAAAANDS
Fixing impulses in array-valued concatenation.
Implementing a JOIN method to stick CHEBFUNs together.

Also initial commit of SOUND and related.
initial commit of SCRIBBLE for v5.
Merge branch 'feature-scribble' into feature-chebfun-scribble
Fix bug in and add test for chebfun.horzcat().

The call to cellfun() which checks to see if there are any different interior
breakpoints was assuming that all chebfuns being concatenated had domain
vectors of length 2.  This commit fixes this issue.  A simple test for
horzcat() has also been added.
Add minimal test for chebfun.repmat().
Minor documentation and style fixes for repmat() and vander().
Fix minor bug in and add test for scribble().

The case for "," had an unwanted space in the string:  ", ".  The test just
ensures that we don't throw any warnings for basic characters and may not be
necessary, but we wrote it anyway.
