corrected issues with changes to dependencies. idq_tables was using an old version of glue.ligolw.table, in which the Table class had a TableName class as an attribute. Now, this is simply a string, and I had to modify idq_tables.py to match the new behavior. Similarly, pdf_estimation relies on scipy's interpolation objects, which appear to now return a 0-d array when called with a float instead of a 1-d array with length=1. This resulted in IndexErrors within pdf_estimation. I've also cleaned up pdf_estimation and changes some of the error handling. Also corrected behavior that led to some warnings but not failures within summary jobs
