Subject: [PATCH] cached up corpusFrecuency

The first time corpusFrecuency is called, we do execute `require('./dictionaries/frequencyListRAE50000.json', 'utf8')` and we store his value in the local `list` variable and in the global `cachedList` variable so in the consecuents calls, we use the cached value

It posibly could be done better, but that was 100% free seccond effect way
