Adding command line script.

Rename of convertion script folder

ulalume3@46	1	""" Sample script to convert licel files to SCC netcdf format.
ulalume3@46	2
ulalume3@46	3	The script assumes the following things:
ulalume3@46	4
ulalume3@46	5	1. You have already installed the atmospheric_lidar module (e.g. using pip).
ulalume3@46	6	2. You have create a class in a file "ipral" describing your system (described the readme file).
ulalume3@46	7	If you want to use it for a different system you need to change the script to use your own class
ulalume3@46	8
ulalume3@46	9	Run the script using: python convert_ipral.py <your options>
ulalume3@46	10
ulalume3@46	11	Examples
ulalume3@46	12	--------
ulalume3@46	13	# This will read all files starting with "l" from "my_dir".
ulalume3@46	14	# It will guess the measurement ID based on the date of the files, and will assume measurement number 00.
ulalume3@46	15	# For example, the new measurment id could be 20120101mb00
ulalume3@46	16	python convert_ipral.py my_dir l*.
ulalume3@46	17
ulalume3@46	18	# This will use the measurement id you defined.
ulalume3@46	19	python convert_ipral.py my_dir l*. -m 20120204mb32 # It will create the file 20120204mb32.nc
ulalume3@46	20
ulalume3@46	21	Help string
ulalume3@46	22	-----------
ulalume3@46	23	# To get this, run: python convert_ipral.py -h
ulalume3@46	24	usage: convert_ipral.py [-h] [-m MEASUREMENT_ID] [-n MEASUREMENT_NUMBER]
ulalume3@46	25	[directory] [searchstring]
ulalume3@46	26
ulalume3@46	27	positional arguments:
ulalume3@46	28	directory Directory with licel files.
ulalume3@46	29	searchstring Processing system id.
ulalume3@46	30
ulalume3@46	31	optional arguments:
ulalume3@46	32	-h, --help show this help message and exit
ulalume3@46	33	-m MEASUREMENT_ID, --measurement_id MEASUREMENT_ID
ulalume3@46	34	The new measurement id
ulalume3@46	35	-n MEASUREMENT_NUMBER, --measurement_number MEASUREMENT_NUMBER
ulalume3@46	36	The measurement number for the date, if no id is
ulalume3@46	37	provided
