web app to create heat profiles

[wang-edward]

sim.py supports following heat profiles, which provides greater accuracy.

Here's an example: Sn63Pb37 solder paste.

it would be cool to have a web app that lets you interactively move around critical points and output a text file.

• Right now we only support straight lines

So for the solder paste it would look like:

0 22
90 150    # soaking zone start
190 180   # soaking zone end
220 220   # reflow zone start
270 180   # reflow zone end

Extra points for clean alignment, e.g.:

0       22
90      150 # soaking zone start
190     180 # soaking zone end
200     220 # reflow zone start
270     180 # reflow zone end
