Rescale the barycentric weights so that the infinity norm is one.
Minor change in documentation.
Making Chebtest --log behave according to its documentation.
Add asymptotic verision of hermpts to hermpts().
Tweek tolerances so tests pass on machine.
Bump up tolerance on test for singfun.rdivide().

This started failing on my personal machine (but not my departmental
workstation) due to some of the recent changes to epslevels.
A stupid mistake caught by AA which made me so embarrassed that I'll be busy killing myself in the rest of the day.
Remove "cosmetic" (?) thresholding line from chebfun.roots().

This closes #1200.  With this line in place, we can get bizarre things
like the following:

  >> f = 1e18*chebfun(@(x) x - 1.5e4, [1e4 2e4])
  f =
     chebfun column (1 smooth piece)
         interval       length   endpoint values
  [   1e+04,   2e+04]        2    -5e+21    5e+21
  Epslevel = 1.238223e-15.  Vscale = 5.000000e+21.
  >> roots(f)
  ans =
       0

Note that the point 0 isn't even in the domain of this chebfun!

An alternative to removing this line like we do here would be to
eliminate the dependence of the threshold on vscale.

Adding removeDeltas feature.
Update pointValues after removing deltas.
Fixes as suggested by @nickhale.

This works both on 2014a and 2014b on my machine (Mac).
Making CHEBGUI work in 2014b as well as previous versions.

This might cause some conflicts with the IVP branch, however,
I'm sure those can be dealt with when the time comes.
Removing 2014b warning.
Adding one more test for removeDeltas.
Reinstating the logo in chebgui.

For some reason, MATLAB keeps making it disappear when changes
are made to the GUI.
