======Synopsis:======
$__strlen__(<string>)

======Technical:======
This function is used to determine the length, in characters, of a given
string.

======Practical:======
This function is effectively the same as the $@var notation, except that
$@var only works for variables, not functions or automatic expandos.

======Returns:======
| >0  | number of characters in string |
|  0  | no string given                |

======Examples:======
<file>
$strlen($1-3)                  returns length of args $1 to $3
$strlen(epic is cool)          returns "12"
