       This plugin uses if-then-else like conditions stored in the metakey check/condition to
       validate data.

   Syntax
       (IF-condition) ? (THEN-condition) : (ELSE-condition) where the ELSE-condition is optional

       Condition: Key Operation `('String' | '1234.56' | Key | '')`

       Operations: !=, ==, <, <=, =>, >, :=, where:

       · := is used to set a key value

       · others are for comparison as in C

   Example
       `(this/key != 'value') ? (then/key == some/other/key) : (or/key <= '125')`

       Meaning: IF this/key NOT EQUAL TO 'value' THEN then/key MUST EQUAL some/other/key ELSE
       or/key MUST BE LESS THAN 125

       Another full example:

       kdb mount conditionals.dump /tmount/conditionals conditionals dump
       kdb set user/tmount/conditionals/fkey 3.0
       kdb set user/tmount/conditionals/hkey hello
       kdb setmeta user/tmount/conditionals/key check/condition "(hkey == 'hello') ? (fkey == '3.0')" # success
       kdb setmeta user/tmount/conditionals/key check/condition "(hkey == 'hello') ? (fkey == '5.0')" # fail
