Message:

#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
