Initial parsing of numbers
Completed NumberReader number parsing
Started Parser string parsing
Additional string value parsing including handling of simple escape codes
String value parsing should be complete
Extracted StringReader & UnicodeCodepointReader from Parser and made them stand-alone classes
StringReader now populates a std::string rather than an Event to make it more generic
Updated to version of clunit.h that contained TCALL() macro
Converted some test function calls to make use of TCALL()
Added additional previously missed error calls to Parser::report_error()
Added JSON 'member' parsing
