Replace pandas by built in csv module

[Enrico Schwass]

To keep dependencies small, do not use external libraries for simple tasks

pandas can be easily replaced by the built-in csv module or even hand-written code

It is even better to store the configuration as json and build the Python objects (RecurringPhaseSequence) from that.
Do not forget to apply meaningful assertions to ensure safe object creation. All outside data is evil.

{

"phase_list": [

{

"title": "Huddle",
"duration": 10

},
{

"title": "Tasking",
"duration": 5

},
{

"title": "Work",
"duration": 45

},
{

"title": "Break",
"duration": 15

}

],
"repetitions": 3

}
