Checks if value
is of type Object and returns true
if so, or false
if not.
let result1 = gmynd.isObject( 270 ); // will return false
let result2 = gmynd.isObject( "Hello!" ); // will return false
let result3 = gmynd.isObject( ["a", "b"] ); // will return true (because arrays are also objects)
let result4 = gmynd.isObject( {x:123, y:456} ); // will return true
