- __gram(): generic binding for C++ to calculate gram() given any kernel. - kernel(): function that returns a kernel instance of a kernel defined by a string parameter. - __get_direction(): transform 0/1 and rows/columns to 1/2.
- __get_directions: now documentated. - All the "private functions" appear now first.
- kernel(s): Returns a Kernel based on the inputs parameters. - Kernel(): Class with the basic functions for any kernel. - Gaussian: Inherit from Kernel and implements a Gaussian kernel.
- Only works with numpy arrays.
- Matern(): Only works with numpy matrices. Doesn't call any C++ code.
- ExpSemigroup: Only works with numpy, doesn't use C++ code.

linear_t(): Extends from kernel_t and implements gram and symmetric gram functions. ckernel.cpp: Linear kenrel exposed.
The expsemigroup kernel has implemented the gram fucntions but not the symmetric_gram yet.
…rix. It workis with El::Matrix and EL::DistMatrix. Not optimized for symmetric matrices yet.
- Utils.py: Contains useful functions for testing.

All the kernels are added and working. However, three of them are not using the C++ implementation (Linear, Matern and ExpSemigroup) because of #13 .
My next task is to implement these methods in C++ and then code the bindings but we can use now all the kernels in python.
