Is there an option to quote std::string (e.g., [" ", ""] instead of [ , ])?

First, thank you, the cxx-prettyprint library is really great. However, I wanted the strings in my output to be quoted, especially non-trimmed strings are otherwise hard to understand.

Example: [" ", ""] instead of [ , ]

I'm not sure if it is possible to customize it with the existing template specializations, so I made some minor modification:

The patch is good enough to solve my specific use case, however, if the option to quote string proves to be useful for others, I would expect there is a better way to implement it. So, no pull request but a prove of concept if others are interested.

Decent idea... One step further would be single quotes for values stored as a single char

Only thing is it would be unlike cout and ostringstream's default behaviour for strings, leaving out the quotes. But it kinda makes sense when printing the full contents of an STL container.
