* Converts arbitrary values into strings using extended conversion rules:
* - Numbers: are converted with '.' as decimal point
* - DateTime: using ISO format
* - Boolean: "true" for true and "false" for false
* - Arrays: as comma-separated list
* - Other objects: using <code>toString()</code> method
*
* ### Example ###
*
* let value1 = StringConverter.ToString(123.456); // Result: "123.456"
* let value2 = StringConverter.ToString(true); // Result: "true"
* let value3 = StringConverter.ToString(new Date(2018,0,1)); // Result: "2018-01-01T00:00:00.00"
* let value4 = StringConverter.ToString([1,2,3]); // Result: "1,2,3"
