regexFindAll

Returns a slice of all matches of the regular expression in the input string. The last parameter n determines the number of substrings to return, where -1 means return all matches

regexFindAll "[2,4,6,8]" "123456789" -1

The above produces [2 4 6 8]

regexFindAll panics if there is a problem and mustRegexFindAll returns an error to the template engine if there is a problem.
