0.2.0 Release

BUG FIXES

1. The non_hash_merge method now correctly returns the results instead of just returning every row.
2. The remove_duplicated selection method now doesn't bug the MainSelection object if soft argument was False
   2 psv.column_names now has proper error handeling for empty files.
3. psv.loads now correctly handles dictionaries, before it would bug the columns

API CHANGES

Removed: The Selection.columns setter has been removed, since it was actually not used internally. Outside access of the variable is not supported, use the addcolumn and delcolumn methods if you need to edit columns.
Removed: Selection.fast_add was just duplicate code to it's __add__, and has been removed.

Change: BaseRow renamed to Row. For backwards compability reasons a variable called BaseRow exists in the same namespace to allow code referencing it to still work.
Change: All psv csv loading functions no longer accept the outputfile argument, it was unused inside the library.

Addition: addcolumn method now supports passing a function that will give it the value to set the newly created column for that row.
Addition: delcolumn method added to allow deleting columns in a supported and safe way.
Addition: update_values added to Row. Built to allow a safe way to use .update() like method on Row instances.
Addition: Added a find family of methods that use the any() function generation code instead of the select method's

Behavior Change: outputtedrows and nonoutputtedrows now use a safe_select(), due to the nature of those functions being a current snapshot and not lazy-loadable.
Behavior Change: Selection.output() now accepts an opened file or io object instead of just a string location of the file. Note: Closes the file within the method.
