* Conditional helper that checks if one value is less than another one.

* My "less" strict inequality is meant. That's why in cases where two equal

* Example of usage:
|

* ```handlebars
|
||||
* {{#ifLess first second}}
|
||||
* The first argument is less than the second one.
|
||||
* {{else}}
|

* The first argument is more or equal to the second one.

* {{/ifLess}}
