/**
Ngrams view which trims the 'input:name' and only uses the LAST TOKEN.
eg. if the input was "100 foo str", then 'input:name' would only be 'str'
note: it is assumed that the rest of the input is matched using another view.
there is an additional flag 'input:name:isComplete' used to disable this view
selectively, see that section for more info.
code notes: this view makes a copy of the $vs object in order to change their
values without mutating the original values, which may be expected in their
unaltered form by other views.
