Add `Merge::CompareFieldsFlag` transform

Enters "same" into target if the value in all fields specified is the same. Otherwise, enters "diff" into target.

downcase true converts all values to lowercase before comparing. strip true removes leading/trailing spaces. Neither option changes the values in fields

ignore_blank true would result in "same" if 2 field values were the same but 1 was empty. ignore_blank false would report "diff" in this situation.

Bugfix for Merge::MultiRowLookup

if there was no key (nothing to look up/match on), crashed because you can't split on nil

Adds `multikey` parameter to `Merge::MultiRowLookup` transform

Adds multikey parameter to Merge::MultiRowLookup transform.

This is set to false by default to make the change non-breaking. If keycolumn value is 'a|b', will merge in values for rows with lookup key 'a|b'.

If set to true (and delim = '|'), will merge in values for rows with lookup key 'a', followed by those with lookup key 'b'

`Append::NilFields` transform class added

Merge pull request #15 from lyrasis/append-fields

add Append::NilFields transform class

Support for %NULLVALUE% handling in Clean transforms

Adds the use_nullvalue transform initialization parameter to Clean::EmptyFieldGroups and Clean::DelimiterOnlyFields

This causes %NULLVALUE% to be treated as a blank value for the purposes of these transforms.

MsAccess::ScientificNotationToNumberString tranform
