Mujir, Praveen| #958 | Moved existing JSSMigrator to use the new csv import framework. Still need to delete old classes, use log4j and multi-threading.
Mujir | #953 | migrator generates error file name. Clients dont need to pass it.
Mujir | #953 | added logging using log4j and error handling.
Mujir | #953 | some cleanup. removed unused vars etc..
Mujir | #953 | writing only failed validation errors to errorfile. No need for clients to explicityly saveErrors after migration. mRefactored to use CSVFile within migrator.
Mujir | #953 | Now that validation and migration are similar, removed some duplication
Mujir | #953 | printing stack trace in error files
Mujir | #953 | Ignoring case for headers. Better exception handling
Mujir | #953 | writing error records to file as and when they occur. Simplified MigrateResult.
