Created script for group-level analysis

Usage example of functions that have been implemented so far:
dwi_group.py FA byStudy --roi lh_vPMC --wmDepth 2 -v
Added new option "--use-fslview"

This option is for the steps inspect_coreg and inspect_parc. If this option is activated, the script will call fslview, instead of tkregsiter for displaying the results.

Usage example:
dwi_analsysis.py CAT 12 inspect_coreg,inspect_tensor,inspect_parc --parc aparc12 --use-fslview

	modified:   dwi_analysis.py
Added new field: groupIDs

This field is useful for group-level analysis (e.g., with dwi_group.py).

Currently, there are three valid groupIDs values:
   nrm for normal
   pds for persistent developmental stuttering (relevant to the STUT and SEQPDS projects)
   sdp for spasmodic dysphonia (relevant to the SDAP project)
Working on the group-level analysis script
Added subject RHY_AWS_F01
mat file writing in dwi_project_info.py
MALTAB code for group analysis
Added new script for getting the master code of subjects
New group-level analysis in MATLAB
Reproducibility analysis for FA patterns

	modified:   dwi_group.m
	modified:   get_tensor_measure.m
Added two subjects to SDAP
Fixed CCRS subjects dir
Added subject RHY_AWS_M04
Added subject RHY_AWS_F04
Added subject RHY_AWS_M05
Added RHY_AWS_M06
Added RHY_AWS_F05
New python scripts for SQL query
Revised the way the py SQL script gets info

A file with the name "mega_sql_settings" needs to be created in the subject's home directory. This file should have four lines, which correspond to
1) SQL server host name
2) SQL database name
3) SQL user name
4) SQL password

e.g.,

two.bu.edu
MEGA
scai
sp1eeCH2

Command line usage example:
get_subject_master_code.py STUT,CAT S05,12
Added new py script for demographic query from SQL

Usage example:
./get_subject_info.py gender --id CAT,RHY,SEQ 12,AWS_M01,SEQ03001
./get_subject_info.py age --id RHY,SEQPDS AWS_F01,SEQ03P03
