Add a command to generate an empty custom template for extensibility

The CLI should expose a command which generates an empty custom template for a framework, which can then be modified to become a full custom template.

The command should allow for framework selection: react, ng, jquery.

ig generate template [name]: Generates custom template in the working folder and the global CLI config file.

• generate: alias g.

• template: alias t

• name: Creates a folder and fills in the id/name. It is optional. Default value is “custom-template”.

--framework=<framework>: alias -f. Selects framework. Default is “jquery”.

--type=<type>: alias -t. Selects the type of the project (framework dependent). Default is “jquery-js”.

--skip-config. Skips registering generated path in the global CLI config. Creates the template in the working folder only.

@sbozalieva I vote for ig generate template-like version or even simply ig custom-template if we don’t plan on future generate additions. So far it looks like two commands (like config), where the main is: > ig generate

• generate: alias g?
• default to template sub-command?

And the only sub-command available for now would be: > ig generate template [name]

• template: - alias t?
• name: Crates folder and applies to id/name. Can be optional with default value of “Custom Template”
• --framework=<framework>: Select framework. Default “jquery” like the CLI?
• --projType=<type>: Project type (dep. on framework) to generate tempalte for. Default “jquery-js” like the CLI?
• --skip-config: Skip registering generated path in the global CLI config
