=head1 kdocParseDoc
Routines for parsing of javadoc comments.
=head2 newDocComment
Parameters: begin (starting line of declaration)
Reads a doc comment to the end and creates a new doc node.
Read a line
check if it changes the current context
yes
flush old context
check if it is a non-text tag
(ie internal/deprecated etc)
yes
reset context to text
set associated property
no
set the new context
assign text to new buffer
no add to text buffer
continue
at end
flush anything pending.
