This function serves as a replacement for the $#var notation when you want to count the words in a string not held in a variable.
This function is used to count the number of words in an arbitrary string. Normally, you could get this value with the $#var form, but that doesn't work for parameter expandos or function return values.
number of words in given string
$numwords(hello there bob) returns 3 $numwords() returns 0
