=head3 matchcount()

Returns the count of a search string Y found in the source string X.

E.g.:

    my $str = "d10d11d1d"; 
    matchcount($str, "d");     # returns 4
    matchcount($str, "d1");    # returns 3

To search for only the string without a regular expression accidentally
interfering, enclose the search string between '\Q' and '\E'. E.g.:

    #
    # We don't know what's in $looking, so de-magic it.
    #
    matchcount($str, '\E' . $looking . '\Q]);
