testing example, need to form this into a framework

scripts/lua/test_cond_api.lua

+-- Test various cond api to verify consistency.
+-- string compared to string (eg. 'string1' == 'string2') compares by value
+-- string compared to number (eg. 'string' == 5) compares its string length
+-- string compared to any type with 'lt(<) gt(>) ge(>=) le(<=)' operators are compared to their legnth (even if both values are strings).
+-- number compared to number works just like you'd expect :)
