Added empty chebyshev algorithms lab.
Merge branch 'master' into cheb
Brought some stuff from the WaveletApps lab over to the Haar lab, since
it is more algorithmic in nature. Fixed small things in the text and
code. Improved the solutions file.
Added new images to the intro to Wavelets lab. Made other smallish changes
to the lab.

Clarified problem no. 1 a bit, included a discussion of how to
empirically calculate convergence, changed problem 2 a bit.
Included a plotFigs file, and a new plot in the lab.
Updated the solutions file.
