Updated the tinc tests to correctly check the eigenvalues of the pca_train function, also to validate the column means output table
Fixed the output tests for pca project, and added the new tests for pca
Add output tests for pca_train where the input matrix is in the column format
Add output tests for pca_project where the input matrix is in the column format
Added the sparse output tests for pca project
Added in the sparse output R script
Updated the dateset table to include the new pca datasets
Minor fix
reverted changes to SVD tests
Minor fixes
Added in tables for pca_project input input tests
