ArgumentError: invalid value for BigDecimal(): "N/A"

[beet]

Steps to reproduce:

When attempting to produce an export when a test is present without enough participants to calculate the statistical confidence, exports raise an exception attempting to convert the string "N/A" to a float.

> csv_data = Split::Export.to_csv
ArgumentError: invalid value for BigDecimal(): "N/A"
from /Users/markb/.rbenv/versions/2.4.0/lib/ruby/gems/2.4.0/gems/split-export-2.0.0/lib/split/export.rb:10:in `initialize'

Could it convert the number to an integer instead of a string to give a value of 0.0?

[5] pry(main)> BigDecimal.new("NA".to_i).round(2).to_f
=> 0.0

@beet maybe we should just rescue and return the string instead?

@andrew great idea.

I was going to create a fork, but rake spec fails with:

NameError:
  uninitialized constant RSpec::Expectations::MultipleExpectationsNotMetError
# ./spec/export_spec.rb:3:in `<top (required)>'

Tried upgrading rspec to 3.x, but can't get the tests to run.

I'm also seeing this exception for tests that have reached statistical significance. Can a patch be released to fix this bug?

Fixed in #18
