     * @memberof Filters#
     * @function addCondition
     * @description
     * Adds condition to the conditions collection at specified column index.
     *
     * Possible predefined conditions:
     *  * `begins_with` - Begins with
     *  * `between` - Between
     *  * `by_value` - By value
     *  * `contains` - Contains
     *  * `empty` - Empty
     *  * `ends_with` - Ends with
     *  * `eq` - Equal
     *  * `gt` - Greater than
     *  * `gte` - Greater than or equal
     *  * `lt` - Less than
     *  * `lte` - Less than or equal
     *  * `none` - None (no filter)
     *  * `not_between` - Not between
     *  * `not_contains` - Not contains
     *  * `not_empty` - Not empty
     *  * `neq` - Not equal.
     *
     * Possible operations on collection of conditions:
     *  * `conjunction` - [**Conjunction**](https://en.wikipedia.org/wiki/Logical_conjunction) on conditions collection (by default), i.e. for such operation: c1 AND c2 AND c3 AND c4 ... AND cn === TRUE, where c1 ... cn are conditions.
     *  * `disjunction` - [**Disjunction**](https://en.wikipedia.org/wiki/Logical_disjunction) on conditions collection, i.e. for such operation: `c1 OR c2 OR c3 OR c4 ... OR cn` === TRUE, where c1, c2, c3, c4 ... cn are conditions.
     *  * `disjunctionWithExtraCondition` - **Disjunction** on first `n - 1`\* conditions from collection with an extra requirement computed from the last condition, i.e. for such operation: `c1 OR c2 OR c3 OR c4 ... OR cn-1 AND cn` === TRUE, where c1, c2, c3, c4 ... cn are conditions.
     *
     * \* when `n` is collection size; it's used i.e. for one operation introduced from UI (when choosing from filter's drop-down menu two conditions with OR operator between them, mixed with choosing values from the multiple choice select)
     *
     * **Note**: Mind that you cannot mix different types of operations (for instance, if you use `conjunction`, use it consequently for a particular column).
     *
