Merge branch 'bashopts_process_opt' into 'master'

- Setup bashopts with ```bashopts_setup``` function

- Declare options/arguments with ```bashopts_declare``` (one call per option)

- Parse arguments with ```bashopts_parse_args```

- Process arguments with ```bashopts_process_args```

- Process arguments with ```bashopts_process_opts```

### Load the library

Load all the function from the ```bashopts.sh``` file and you can add the line ```trap 'bashopts_exit_handle' ERR``` to display backtrace on error

 - ```-d <val>```: Tool description

 - ```-u <val>```: Tool usage (optional)

 - ```-s <val>```: Define a setting file path (optional)

 - ```-f```: Force edition for interactive options (default: a prompt is displayed only if not given via the command line)

 - ```-y```: Set non interactive mode as the default mode (optional)

 - ```-x```: Disable entirely interactive mode (optional)

 - ```-p```: Force value storage even if the value is equal to the default one (optional)

Code example:

```bash

```

### Argument processing

Process all the options with ```bashopts_process_args```

Process all the options with ```bashopts_process_opts```

This function will fill all options values using the following order:

- Value from the command line

- The default option value (may be defined with the ```bashopts_declare -v```)

bashopts_process_args usage:

bashopts_process_opts usage:

```bash

bashopts_process_args

bashopts_process_opts

```
