[boost] [Tokenizer] A hybrid between char_separator and escaped_list_separator

It would be very useful to have a tokenizer that operates similar to the regular char_separator, but also handles delimiters in quoted portions like escaped_list_separator. For example: Input: model name = "My Model" label="A short label = A good label" parts= 3 Output: <model> <name> <=> <My Model> <label> <=> <A short label = A good label> <parts> <=> <3> Regards, Zvi Tarem (zvi.tarem@cern.ch)
