## Description

Also a good idea to check with dentaku maintainer about helping with documentation, as it is minimal there.

Few small changes to operators/functions were also made:

*   Added `==` as an alias for `=`
    
*   Added `&&` as an alias for `AND` and `||` as an alias for `OR`
    
*   Removed `COUNT` function, as it doesn't really make sense without support of arrays/lists, it just gives the number of arguments which is static in the formula (`COUNT(1, 1, 1, 1, 1)` => `5`)
