ArraySize is needed in customFunctions I think.

Here's my custom funciton below. You can see it accepts either 1, 2, 3 or 4 arguments.

If the first parameter is financialStatements then I need to tell hyperformula to return an ArraySize so that it can overflow into subsequent cells.

  // Pre-fixed with TT due to there already being a FinancialPlugin
  // in hyperformula
  class

x^{2} instead of x^2, \log_{2}(x) instead of \log_2(x).
Makes output more consistent and easier to parse with no special cases for single characters. E.g. x^{12} must be written like that.
Also consistent with MathQuill.
