Add ultraS/expm
Remove collocation from linop/expm. First attempt at ultraS/expm.
Another go at ultraS/expm
Update toValues, so that ultraS can get the ChebT coefficients.
Block up the conversion operator.
Tidy up.
Add vertical scale commands
Fixing a bug in figuring out the ylim when the tech is array-valued.
Giving some extra space at the top and the bottom margins.
For a finite-valued chebfun, let Matlab decide the xLim and for a chebfun defined on a bounded domain, let Matlab decide the yLim.
Allow construction from logical (convert to double).
Split chebfun2v roots tests into smaller chunks.
Merge branch 'development' of ssh://github.com/chebfun/chebfun into fix-ylim
Fix when scalar problem CHEBOP is passed a CHEBMATRIX input.

Closes #784.
Fixing a minor bug, that caused YLIMs to be set unnecessarily.
Merge pull request #791 from chebfun/fix-chebop-feval2

Fix when scalar problem CHEBOP is passed a CHEBMATRIX input.
Adding better documentation to SCALE methods.
Fixing a few bugs introduced in the last push.
Allowing subclasses of CHEBDISCRETIZATION to specify their own
dimensionValues strategy.
