Cannot convert empy cell to number

[arnaudroger]

Hi there, I'm trying to integrate your csv reader in https://github.com/arnaudroger/mapping-benchmark/tree/master/sfm-csv

it tries to parse

http://www.maxmind.com/download/worldcities/worldcitiespop.txt.gz
to
https://github.com/arnaudroger/mapping-benchmark/blob/master/sfm-csv/src/main/java/org/simpleflatmapper/City.java

but fails on all the other parser works well with that.

Exception in thread "main" org.csveed.report.CsvException: Problem converting cell index 5 (E) [] to population: java.lang.Number
2: ad,aixas,Aix�s,06,,42.4833333,1.4666667\n
