@description:
Creates the SampleSheet.csv out of values from openBIS for Demultiplexing 
used in the Illumina pipeline (bcl2fastq) 

@attention:
Runs under Jython

@note:
Takes into account to replace special characters with an underscore so that the Illumina script
does not fail

HiSeq Header Description
========================
Column Header  Description
FCID  Flow cell ID
Lane  Positive integer, indicating the lane number (1-8)
SampleID  ID of the sample
SampleRef  The reference used for alignment for the sample
Index  Index sequences. Multiple index reads are separated by a hyphen (for example, ACCAGTAA-GGACATGA).
Description  Description of the sample
Control  Y indicates this lane is a control lane, N means sample
Recipe Recipe used during sequencing
Operator Name or ID of the operator
SampleProject  The project the sample belongs to
