Finished coding for elastic Gaussian IGD
Finish coding elastic net for linear models using IGD
Elastic Net: Added argument validation, and support for normalization =
False
Elastic Net: Added short help message for igd
Elastic Net: Started adding documentation
Elastic Net: Continue writing documentation
Elastic Net: Documentation, Prediction function

Documentation is finished.

Move the prediction function from C into Python, so that a universal
interface can be used for all models.
Elastic Net: Corrected small bugs, added iteration_run in the output

iteration_run can help the user to know whether the tolerance criteria
is fullfilled.
Elastic Net: Use MSE difference between two consecutive states as
stopping criteria
Elastic Net: Finished batch coordinate descent method

Implemented R package glmnet's algorithm.
Elastic net BCD: updated the short help messages
Elastic Net BCD: Corrected a bug that seems to affect GPDB

Cannot assign sq to be length dimension-1, instead use dimension.
Elastic Net: Added Null values checks
Elastic Net BCD: Fixed a typo that decreases log_likelihood
Elastic Net: Update docs and comments

Changed "regulation" to "regularization"
