 I have just started using boost Locale and it is a great addition to the
 boost library.  However, the collation level options do not give a fine
 enough control.  From the ICU documentation:  "In some cases, punctuation
 can be ignored while searching or sorting data...In other cases, it is
 desirable for punctuated text to be distinguished from text without
 punctuation."  (This appears to be controlled by the Alternate attribute.)

 However, boost Locale seems to always assume that punctuation can be
 ignored when you are also ignoring case.  In particular, I find at the
 secondary level that "SINWAVE" is considered equal to "sin_wave" (compare
 returns 0) when this is not what I (and very likely others) require.

 The first two levels (primary and secondary) really need options to not
 ignore punctuation and whitespace.
