Cleaning up problems in the OPL, there are a number of places that \begin{align*} \end{align*} are used inside of latex blocks. Often in SOLUTION blocks.

These typically render okay in the browser with MathJax, but will produce errors when making a hardcopy.

This creates a pg-critic file to flag this.

Note, these will also fail now if wrapped inside another environment, such as displaymode, [``\begin{align*}...\end{align*}``]. I had a lot of broken problems because MathJax 4.x will only allow align* to be a top level environment (while 3.2 didn't have this restriction), and nesting it in display mode or anything will cause MathJax to fail to render it.

This generally looks fine. Just a few minor details to fix.
