Simple scripts for file (mainly csv) manipulation
##ruby simple vlookup implementation
temp = vlookupHash(file: file, key_separator: '#', key_fields: ['Col1','Col2'], fields: ['Field1','Field2','field3'])
file: source file, key_fields: fields used to lookup key, fields: fields you want to get from the file key_separator: you can specify how the key values will be joined. The example above will produce Col1#Col2 as key
