[brandonscholten]

Changes made:

• using waitress to better handle multiple requests at once
• additional CLI features
  • configurable server address and port
  • allow for the user to specify acceptable abbreviations
  • soon acceptable abbreviations and acceptable words will be separate
• A docker container can be used to run the tagger and automatically pull a list of acceptable words which will be labeled as dictionary words
• Changed output to the following JSON format:

{
  "count":1,
  "firstEncounter":1732639776.5735562,
  "lastEncounter":1732639776.5735579,
  "version":"SCANL 1.0",
  "words":[
    {
      "identifier":{
        "dictionary":"DW",
        "tag":"NM"
       }
    },
    {"Name":{
       "dictionary":"DW",
       "tag":"N"
       }
    }
  ]
}

• Added result caching to improve speed
• Added a dictionary word lookup
