Subject: Full support for arrays => min, max and avg funcs accept array
 argument. Also array function is defined which return arguments as array.
 Square bracket arrays are also supported. (#108)

valid expression -> "max([1,2,3])"
valid expression -> "max(array(1,2,3))"
valid expression -> "max($ages_arr)"
valid expression -> "max(ages_arr())"
