made each insert a println instead of print so the files are easier to work with
changed formatting of output so we could output null for a missing abstract
made the pub date null when dumping so the insert would work. Checked if there was an abstract before getting the text to avoid a null pointer exception.
added constants fore single and double quote - considering switching single to double insterad of eliminating
when formating a string, replaced linefeeds with a space so words do not combine.  had to then add to replace 2 spaces with 1. commented out removing periods - need to check with Xiaozhong on that.
added .classpath and pubmad directory for dump files to the list of files to ignore
