Adding command line script.

Rename of convertion script folder

binietoglou@42	1	""" Sample script to convert licel files to SCC netcdf format.
binietoglou@42	2
binietoglou@42	3	The script assumes the following things:
binietoglou@42	4
binietoglou@42	5	1. You have already installed the atmospheric_lidar module (e.g. using pip).
binietoglou@42	6	2. You have create a class in a file "lilas" describing your system (described the readme file).
binietoglou@42	7	If you want to use it for a different system you need to change the script to use your own class
binietoglou@42	8
binietoglou@42	9	Run the script using: python convert_lilas.py <your options>
binietoglou@42	10
binietoglou@42	11	Examples
binietoglou@42	12	--------
binietoglou@42	13	# This will read all files starting with "l" from "my_dir".
binietoglou@42	14	# It will guess the measurement ID based on the date of the files, and will assume measurement number 00.
binietoglou@42	15	# For example, the new measurment id could be 20120101mb00
binietoglou@42	16	python convert_lilas.py my_dir l*.
binietoglou@42	17
binietoglou@42	18	# This will use the measurement id you defined.
binietoglou@42	19	python convert_lilas.py my_dir l*. -m 20120204mb32 # It will create the file 20120204mb32.nc
binietoglou@42	20
binietoglou@42	21	Help string
binietoglou@42	22	-----------
binietoglou@42	23	# To get this, run: python convert_lilas.py -h
binietoglou@42	24	usage: convert_lilas.py [-h] [-m MEASUREMENT_ID] [-n MEASUREMENT_NUMBER]
binietoglou@42	25	[directory] [searchstring]
binietoglou@42	26
binietoglou@42	27	positional arguments:
binietoglou@42	28	directory Directory with licel files.
binietoglou@42	29	searchstring Processing system id.
binietoglou@42	30
binietoglou@42	31	optional arguments:
binietoglou@42	32	-h, --help show this help message and exit
binietoglou@42	33	-m MEASUREMENT_ID, --measurement_id MEASUREMENT_ID
binietoglou@42	34	The new measurement id
binietoglou@42	35	-n MEASUREMENT_NUMBER, --measurement_number MEASUREMENT_NUMBER
binietoglou@42	36	The measurement number for the date, if no id is
binietoglou@42	37	provided
