Nested helpers

Nested helpers refers to having a helper inside another, this enables you to use multiple helpers on a token. Nested helpers can be used to address requirements such as “capitalizing the number converted to words”, “sorting comma-separated employee names” and “applying discount by percentage on invoice total”.
Example 1:
{{capitalize (number_to_words amount suffix="dollars" decimal_suffix="cents")}}
Input
Output
800.658
Eight hundred dollars six hundred and fifty-eight cents
Example 2:
{{divide (subtract a b) c}}
Input
Output
a b c
50 10 5
8
Note that nested helpers should be written inside the parenthesis () and not inside curly braces {{}}.
