Load data into tables

To make sure, that diagnostic is able to process a log file without the need to recompile it with an adequate regular expression, the regular expressions + field definitions have to be managed in a configuration file.

This configuration file needs to map a log file type on columns and a regular expression.

This looks like this:

[
  {
    "type": "travis_log_last_2000.log",
    "columns": [
      "severity",
      "date",
      "message",
      "component"   
    ],
    "regex": "..."
  }
]

When a log file gets read its data gets stored in a table like structure.

Maybe it makes sense to map each field on a regular expression. Then it gets easier to extract the things we are actually interested in.
