json-cpp Code

Added empty() operator-bang and isNull()

Added removeMember() and altered a few comments.

Added/clarified comments. Move extra verbiage out of brief sections.

fixed compiler warning

setComment() will assert if comment does not start with / (or if it were NULL, which would have seg-faulted before).

Added comments, pre- and post-condition for resize(), clear(), Value(ValueType).

[1611376]by reserving the max string-size when escaped chars exist, we should save some runtime.

[1611376]writer now escapes special characters. When no special chars are present, old behavior is retained. New method might have a performance penalty b/c of operator new inside std::string. (This would not exist if the whole thing operated on ostream instead, I think.)

[1587188]Fixed parsing of comment at tail of object.

Fixed gcc 2.95.3 problem. Bug: 1570919
