moved progress_bar function from hek2vso module and created a module in the sunpy.util directory
adding WSDL parser functions
__init__ update
fixed minor data-type error and fixed errors in the __init__ files I wrote.
polished the parser module and began fleshing out the hec module. Currently returns a beautiful VOtable obejct containing the hec table names for a query.
Added: function to convert time objects to format supported by the HELIO WSDL service, filled in the time_query method, created a method to prompt user with a choice for table names and feeds it into the HELIO service, plus a couple other smaller methods to clean and format results
