Development guide could benefit from code examples

[KristijanArmeni]

The problem

The development guide is a great starting point for anyone wishing to contribute. But it could use some code examples added in the markdown text (instead of just links to GitHub code)

Possible implementation

For example when it gives an instruction like this:

Add all the defined modules to the suite.

It would be more user friendly to also show an example code snippet (or pseudocode) below:

Add all the defined modules to the suite.

suite = AnalyzerSuite(
    all_analyzers=[
        example_base,
        example_report,
        example_web,
        ngrams,
        ngram_stats,
        ngrams_web,
        time_coordination,
        temporal,
        temporal_barplot,
        hashtags,
        # <--- add your analyzer here
    ]
)
