1. Use ADS and make a list of papers.
2. Save the collection as a private library (useful, should you wish
   to redo the exercise)
3. Export the library using "Other Formats" and within that choose "Custom 
   Format" and type in "%R, %c" (the quotes are not to be entered) 
   in the "Enter Custom Format" box.
4. Save the output as, say, Author.dat
5. Save your ADS Token in file "ADS_Token"

Programs: Gen_ACR, bc2authors, HistogramAuthors, InquiriesLeft

STEP 1: Generate list of bibcodes for refs and cites
$ ./Gen_ACR Author.dat   

	# output files:
	# bc.dat      ... list of bibcodes of author with citations>0
	# ref_bc.dat  ... list of bibcodes of papers referred to be the author
	# cite_bc.dat ... list of bibcodes of papers citing the author
	# CA.dat .. list of co-authors of the author

STEP 2: Obtain a histogram of co-authors
$ ./HistogramAuthors CoAuthor.dat > CA_hist.dat
			
STEP 3: Build list of authors of citing papers
$ ./bc2authors ref_bc.dat       #output: ref_bc_nnn.dat

STEP 4: Build authors of reference papers
$ ./bc2authors cite_bc.dat      #output: cite_bc_nnn.dat

STEP 5: ./BuildAnalyze
