I am trying to fit an optimized Gaussian distribution over a histogram of observed values via scipy (scipy.optimize). The data sample is random floats from 0 to 100. The Gaussian is optimized to find the parameters (mu,sigma,normc) that give the minimum chi-square. The chi-square is calculated b...

Not bad for a first program.
You do formatting work in a couple of places, most notably in getLine(). What does "getLine" even mean? In this context, it only gives you half a line! I recommend deferring formatting until as late as possible, since stringifying data degrades it and makes it less...

Which is better in this case, use auto or TilePosition?
for (const auto& meterTilePosition : meterTilePositions) {.....}
In my oppinion it looks way better if you write code in multiple lines if there is more than one parameter.
e.g. I would prefer:
$unit = new Unit(
request('name'),
request('description')
);
over this:
$unit = new Unit(request('name'), request('description'));
