#3026

  • added ResultFormatter to add an extra layer of result transformation logic (converting a result value to a string with a defined logic, e.g. MatlabResultFormatter for ISymbolicRegressionSolution)
  • extended the IResultJsonItem with two properties for result formatting
  • added a new control to selected a result formatter for a result value
  • refactored the Runner for the new result formatting process
