Make numbers more readable in a Rails view

Rails has a number of handy helper methods.

Specifically, in ActionView::Helpers::NumberHelper there is the method number_with_delimiter

If you want to display the number 100000 and have people know right away whether it is 1 million or 100 thousand, just pass it to number_with_delimiter and it will return "100,000".

Some useful optional keyword parameters:
delimiter:"🍔" replaces the default , delimiter. (100000 becomes 100🍔000)
separator:"🍕" replaces the default . separator. (100.56 becomes 100🍕56)
