added clarifications to tutorial
added examples
added examples, info about semidefinite, and updated readme
updated readme so need to go to cvxpy.org
fixed typo in readme
typo in intro
added mul_elemwise
added mul_elemwise to docs
changed mul_elemwise to promote scalars
making kktsolver sparse
cholmod ldl factorization not working as well as lapack.sytrs
abandoning effort to convert cvxopt kktsolver to sparse ldl
using an invalid solver now raises an error
added reshape atom
updated docs on constraints to clarify chained constraints issue
working on total variation function
finished tv atom
Merge remote-tracking branch 'upstream/master' into judsons_examples
Example clock_mesh: Convert to use reshape atom.

The reshape atom was recently added, and makes the constraint
formation in this problem much cleaner. Result is the
same, except for negligible differences in the solution. The
result plots are identical.
Example fir_chebychev_design: LaTeX the title

The H(w) in the title was converted to a LaTeX math expression,
replacing "w" with "\omega".
