Implement column mapping generator

[umed]

Implement mapping generator. Mappings describe how tables will be presented in the database.

As input should take Excel file with following columns:

Link	File name	Format	Table name	Department name	Uploading type

As output should produce Excel file with following columns:

Table name	Code	Name_rus	Data type	Length	PK	FK	Check Null	Comment

It must be module on uploader level with mapping_generator name.

Create folder named mapping_generator in the root of project.
Reuse uploader/excel_helper.py. It has function named read_excel that tuple of two items:

• Columns info
• list of maps. each map is row from the file.

mapping_generator must be usable either as library or executable module.

As library there should be function that we can import and call it with arguments:

• path to input file
• path to output file

As executable use argparse and add to two params as described above.
