This PR does 3 things:

Allow compile-time setting of printing precision (number of places for the error; cligen/strUt.fmtUncertain rounds value to same decimal).
Pi -> PI because that is how std/math.nim spells it. This lets users do nim c --hint:Name:on --styleCheck=error --styleCheck=usages.
Add inverse-var weighted averaging operator & varargs/openArray reducer with a URI justifying the weights.
