Signature
String nibble(String& haystack, String delim)
Parameters
haystack : string to be nibbled at
delim : delimiter
return value : string before first occurrence of 'delim'
Returns the part of haystack before the first occurrence of delim.
As a side effect, the consumed portion is removed from haystack, including the delimiter itself.
If delim does not occur in haystack, the entire string is returned and haystack is set to an empty string.
