check to see if if ycoc-055 indicators have one to one correspondence with value (B) variables
added choice data
discovered bug related to discrpancies between two YCOC-055 lists
fixed bug caused by uneven lists, discovered that year does seem to matter in loops. for schools where there is a no info yet tag in the indicator, we should look at DLI questions
runs pulling only exact year match data. runs slowly.
added reading in of YCOC DLI variables
added function that checks into DLI variables, untested
temporarility removed GEO fin aid population section. added compelte list of all YCOC variables that match college type
moved everything into functions and introduced recursion in the getAid function. testing required
fixed global assignment of variables in getAid funciton
implemented vector method for extracting all possible aid information before attempting to aggregate
added loan and other amount sto getAIdYSCH. completed pull of finance data
added aggregation of choice data. still need to fill missing values
added check for denial of aid receipt. added multipltying and dividing by 100 to get  more matches on school id's
added setting to zero whenever there is a 2 in the changed mind variable and allowed filling in of missings with the attended data
tried adding a check for a negative 2 in the changed mind variabe, but did not yield expected results
changed update of YCOCEst from YSCHEst so that the min estiamte is always taken if YCOCEst is less than 0. This is because less negative missingness values are more meaningful and we can now test whether the 2003 missings with the ID appearing in PREV variables mostly have -2 in their changed mind variable
discovered that some people report financial aid amounts without reporting an indicator. These should still be used
