FDS Source: Do not allow + sign in labels

These restrictions should be added to the Guides.

I can see why a "," might cause an issue when we go to read a csv file but what is breaking with a "+" sign?

[mcgratta]

The comma restriction is in the guides, now. I'll add the +. It is because our Matlab/Python scripts take the + to mean that two columns are to added together.

[drjfloyd]

Is there another symbol or something we could use in the script to add columns? ++? A single plus is a handy item labels at times.

[mcgratta]

I did not find any + signs in the FDS V&V cases, and only a few in the experimental data sets. I prefer to wait until we've converted from matlab to python because we don't want to introduce any other sources are error.

[drjfloyd]

I have used + in many inputs outside of V&V runs. Things like "X +1 m" where X is some location in the domain or "X+Y" where I have a CTRL that sums X and Y and a DEVC that outputs the result. For making plots where you want to use the DEVC ID as the plot label, not having "+" could mean needing more complex or less intutive labels.

[mcgratta]

What has probably happened is that we used to put double quotes around the DEVC column heads. That forced us in some Matlab scripts to parse the headers and eliminate the quotes. Not going over the Python, we're finding conflicts with the + syntax. We would rather not put any quotes into the .csv files, so we might have to make some sacrifices on column names to avoid complicated parsings.
