yatsm: Yet Another Time Series Model (YATSM): v0.5.0

Very backwards incompatible release required to redefine project objectives and use better technology (click & YAML) for command line interface. See milestone v0.5.0 for individual tickets.

Highlights include:

• CLI conversion to use click #28
  • All sub-commands listed with yatsm command for better visibility
• Redefine YATSM as baseclass & add CCDCesque implementation #29
• Specify prediction algorithm using pickles to set hyperparameters #26
• Configuration file using YAML for easier organization & more sustainable parsing #30
• Refactored robust fit into more generalized refit step. User can refit using specified prediction algorithms #33
• Addressed requirement file organization and documentation, including adding conda install instructions #32
• Tests now use py.test fixtures for better code reuse; test coverage decrease unfortunate side effect

Inevitable bugs will be fixed in v0.5.1.
